Hi, thanks for the report. Sorry to inform you that the problem is still there. Even when not behind a proxy the GetAsync will fired the requestdone even when not ready causing the next call to generate an exception HTTP component is busy Are you able to reproduce the issue with OverbyteHttpAsy demo? Is it an URL publicly accessible? If yes, please send me that URL or post it to this list. Maybe the reason is not related to redirection and proxy usage at all? It's an page request that generates a 301 status. HttpAsy is not a threaded application, seems there the same url will then not generate a problem. HttpThr1 doesn't do a async call so again no problem. I can send you a few links but then again I do not know if those always generate that error.

Re: [twsocket] HttpNoBasicAuth
it's time for a rewrite from scratch IMO. And give it a different name, to bypass the no brake early code rule, or some of the annoyances will have to remain. Or start a new branch of renewed components. And, IMHO, if technically possible, the THttpCli should mix HTTP and HTTPS, and handle internally what protocol to use, based in the current URL, that can originate from an usual HTTP to HTTPS redirect. In my opinion, the future cross platform Delphi which will come sooner or later (hopefully sooner) will be the best candidate for a rewrite. It will be ICS V8. Given the fact that even the basic function (GetASync) is broken and hard to correct IMHO waiting for a next version of delphi is to late to start ( planning ) a rewrite. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

I will make time next week to test together with the user that had the problem, so I know for sure it is solved :-) In the mean while i wrote a workaround by recalling the get and resetting the proxy values when a 407 was received.

Update : Seems there are still scenario's where the problem returns also sometimes the proxy settings are lost creating a 407 when a relocation happens. Seems to happen when executing a GetAsync and a relocate is triggered (with follow relocation set) Thanks for the report. That's probably because SetReady is skipped with it's code related to proxy and www-authentication :( The HTTP component is a TRUE beast. Yes, it is! Is there not something like a full-blown http test tool which we can run against it and then start rewriting some parts to get it back in it's cage ?

Re: [twsocket] HttpCli / Async in thread problems --- Tryng to trace
You are right, I did not test the GetAsync, in async mode
RequestDone is actually fired with StatusCode 0 after relocation.
Triggered by a call to CheckDelaySetReady in GetBodyLineNext.
When I add a check for FLocationFlag there it _SEEMS_ to fix it,
has to be still tested very hard in order not to introduce new bugs:
TriggerDocEnd;
if {(FResponseVer = '1.0') or (FRequestVer = '1.0') or }

(FCloseReq) then { SAE 01/06/04 }
FCtrlSocket.CloseDelayed
else if not FLocationFlag then // == Try this change and
test, test, test...
CheckDelaySetReady; { 09/26/08 ML }
I tested it and it seems indeed to solve the problem. I spend several
hours extra trying to read and understand the reason behind this but

Hi all,
We've been using ICS for quite a while now, but recenlty we've come at
the point that we hit the limit of 10 'half-open' connections introduced
in Windows XP SP2.
See:
http://www.microsoft.com/technet/support/ee/transform.aspx?ProdName=Windows%20Operating%20SystemProdVer=5.2EvtID=4226EvtSrc=TcpipLCID=1033
In an attempt to avoid hitting the maximum of 10 'half-open' connetions
(meaning status is SYN_SENT, client sent SYN, but did not receive ACK
(yet)) when trying to build up
a lot of TCP connections, I'm limiting the time each connection has to
'get connected'.
I download some software to patch the system file http://lvllord.de/

[twsocket] Httpcli cookie
While the discussion for the urlencode on autorelocate is going nicely :-) I also have a small remark to make about the cookie property. Currently the following is done when a cookie is received - else if Field = 'set-cookie' then begin bAccept := TRUE; TriggerCookie(Data, bAccept); end - would it not be beter to save the recieved cookie somewhere in the httpcli component? I believe that this cookie-property is the only received property that is not feed back into the component when recieved. Currently I handle this in the oncookie event but that means that I have extra variables laying around for every httpcli component I use and i really not like that. It's a kind of weird that after a get or post I need to access on variable to see the real returned cookie value. I have the code available so i can propose the change but would like to see some comments on the basic idea first Kind regards, Frans -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Httpcli cookie
From: Francois PIETTE Normally, cookies are managed by the application. It is not always that simple because of path and expiration. You can have a lot of cookies grabbed from one or even several URL while redirecting. So you should really write some manager code to have cookies somewhat persistant. That's why the event pass the cookie thru an event and do not store it in the component. Note that you can derive your own HTTP component from ICS component and add the storage or manager you like. In my opinion, it is better to write a separate class for cookie management and link that class to your HTTP component. A cookie manager component would be a nice addon to ICS :-) Yes, deriving would be an option, did not think about that one. But just recently I came across some weird and wonderful websites that did non-standard thinks to the cookie, so far for bad excuses :-) How would you add to the current httpcli (v6) component a cookie-manager in a non code breaking manner as the current cookie is defined as a string? I'm willing to spend time on writing a rudimentary manager as this would add more value the your component and it's a nice way to contribute something other then the postcard :-) -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Write a TCookieManager component. Create a new property CookieManager in the HTTP component. At design time, link the cookie manager component to the http component. In the http component, when a cookie is received and the cookie manage is assigned, the HTP component call the appropriate methods in the cookie manager. The same when a request is sent: if cookie manager is assigned, the http component request the cookie manager to get the cookie list to add to the request. Nice, agreed. I will add this to my list. As soon as a first version is available I will post it here. For all readers, if you can think of any cookiemanager functions etc, just list them and I'll see what I can do.

From: Francois PIETTE For all readers, if you can think of any cookiemanager functions etc, just list them and I'll see what I can do.

Re: [twsocket] httpcli v6 bad request
Notice that replacing spaces may not suffice, as it may fail too if any other unencoded character is included; so if you want HttpCli to handle it, I would suggest rather a call to an HTML-Encode function for the URL prior to posting the response. However, I still think that this should go at the point of actually sending the response, to make sure that *any* URL requested is encoded properly, regardless of where it was captured (user, redirect response, etc.). dZ. Or allow to do it yourself at onrelocation event but as stated before that event is constructed such that it does not allow access to the url. So either a new event at the correct point or a automatic urldecode call to format the url correctly. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] httpcli v6 bad request
Frans, As I mentioned before, replacing spaces will still leave you open to other invalid characters. If you want a quick fix for your current problem, then I suggest URL-encoding the entire URL instead of just the the spaces. Its been a while since I've used HttpCli, so I'm not sure if it provides one, but creating a URL encoding function is not that hard (its basically turning every invalid character into a code of the form %XX where XX represents the ASCII code for character in Hex), contact me privately if you need help with it. thank you for the offer. Urldecode and Urlencode are present in the ics library so that is not a problem. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] httpcli v6 bad request
my 2 cents on this :
If you feed Thttpcli.url with a invalid url no urldecode is executed. To
keep consistency in behavior I would not just do an automatic urldecode on a
relocate.
The main issue is however that with the followrelocate set it will generate
an error while a browser will not.
To allow a programmer to make a decision on an invalid relocate url the
component must provide an option to do so.
I therefore see 3 possible solutions.
1) A new property AutoDecodeRelocationUrl type Boolean. Default FALSE. If
set TRUE will execute a urldecode on the relocate AND possible on the
httpcli.url also. But if it include the later option as well the name maybe
should be AutoUrlDecode.
2) A new event OnRelocationRecieved(data : String; Accept : Boolean) to be
called around line 2675 (procedure getheaderlinenext)

This would allow the programmer to temporary overrule the FFollowRelocation
setting on demand but also allow adjustment of the received header data. I
think that would enhance flexibility.
3) A change to the procedure getheaderlinenext to just change the received
data. In my opion not the best option as it can cause confusion about what
is really received.
Feedback appreciated :

Re: [twsocket] httpcli v6 bad request
Francois,
I constructed a 301 page for you at www.hedaal.nl/tmp/fromhere.asp
If you use IE this link will relocate you to
http://www.hedaal.nl/tmp/to%20here.html
If you use OverbyteIcsHttpTst it will give you a 400 Bad Request because
of the space in to here.html
The asp code for the fromhere.asp is
-
p = http://www.hedaal.nl/tmp/to here.html
Response.Status=301 Moved Permanently
Response.AddHeader Location, p
Please note that the following will cause the server to include a %20 before
sending the header
p = http://www.hedaal.nl/tmp/to here.html
response.redirect p

Re: [twsocket] httpcli v6 bad request
That appears correct, the THttpCli changes a POST to a GET request when automatically redirecting. RFC1945 however say that this is wrong: That's true. We found the same thing while building an interface to one server. Note, however, the major browsers all change the POST to a GET. The server we interface with, in fact, expects a GET at the location it redirects us to with the 302 response. I remember long time ago we discussed this topic (post changed to get after relocation) and we concluded that it must be done so because most browser do not follow the standard and not doing like the browser will result in failure. That is probably how a bug in a well known browser become a de-facto standard ! Like it or not, if you don't do the same, your program will be accused of malfunction even if it perfectly follow the standard. Is it possible that httpcli will not send/set the cookies after recieving a 302? I think that might be the reason for recieving the bad request response. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] httpcli v6 bad request
Tested it without firewall etc. The first postasync generate 302 from the server. As follow is set the httpcli will also do a get for the relocation. after processing of the result of that relocation the second postasync to the same server will generate again 302, follow is set. This time in the code I see the response bad request. In the sniffer I will however see the 302 (as expected) but there is no additional get to relocate send out by the software. So it seems that after receiving the 302, the thttpcli tries to generate the correct values to do a relocation and fails somewhere/somehow?

Re: [twsocket] Confirming an Abort in THttpCli
I have a multi-threaded application that uses a dynamically created THttpCli synchronously. I know that ICS is normally used asynchronously, but I could not determine a good way to handle that with all the dynamically created threads I have to use for database access anyway. When I want to terminate the thread normally or when I force it to terminate I call the THttpCli.Abort method. How can I insure that the THttpCli component is indeed aborted before freeing it and ending the thread? Right now I do: HTTP.Abort; while HTTP.StatehttpReady do Sleep(10); Is this incorrect, unecessary or adequate? I was getting some ICS errors when freeing the thread which may have been related to freeing the THttpCli or the underlying receive stream. Thanks, -Johnnie Norsworthy Johnnie, I did the same thing (except for the sleep) but keep getting troubles with the abort (hangs). The sleep I did not because I called the abort outside the thread and you don't want to sleep the main thread! I guess you also call it outside the thread as you use a sync call in the thread :-) I changed to async calls but with the http.CtrlSocket.MessageLoop to mimic sync behaviour. And for the abort I then used the PostMessage(Http.CtrlSocket.Handle, WM_QUIT, 0, 0) to kill it. Never had any troubles again! Nice thing is that my multihreaded app is now showing much beter cpu load then with the sync call ! -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

I have probably misunderstood something because I get the same behavior described below no matter which of the components SmtpCli, SyncSmtpCli and HtmlSmtpCli I use. The problem has to do with freeing the smtp-components parent form. You can easily duplicate the behavior with one of the standard demo applications: * Open Your favorite demo of MailSnd, MimeTst or MailHtml. (I proceed with MailSnd-demo below.) * Add a new form with a button to the project. Write the following in the buttons OnClick method: procedure TForm2.Button1Click(Sender: TObject); begin SmtpTestForm := TSmtpTestForm.Create(Application); try SmtpTestForm.ShowModal; finally SmtpTestForm.Release; end; end; When entering the second time is the form already released then?

Re: [twsocket] Freeze when using smtp after recreating itsparentform
I normally just call .free never used .released. You have to use Release when called from an event handler which originate from the form you are freeing. Release make sure all curent events are processed. Free does an immediate free which will crash the application if one event handler is still running.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Hi Frans! Yes, each time You press the button the form is created and then released. You also get the same problem if You set Action to caFree in the OnClose of the created form. Sorry, for not expressing myself any better. My question was If you run the debug and while entring the buttonclick is the .release finished so did you find the form to be free-ed already and my second remark was If you replace the .release with .free is the problem still there?. My final remark was that I normally have the form as a procedure variable as it is not needed to be defined outside the buttonclick event and maybe that also solves your issue. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Dec(WSocketGCount);
if WSocketGCount = 0 then begin

I don't know what I did wrong for this AE to be thrown. I can't even
catch
the exception. This happens all the time on my machine but on most

I cannot give you more details on the architecture of my app right, but

Francois Piette wrote: I don't know of ANY component where it is safe to call the message pump from one of its event without knowing what happend. Even for a simple TButton.OnClick, you can get strange result if you call the message pump within the OnClick handler because the handler is re-entered. The problem is more visible with TWSocket since it is likely the event is always reentered because of the high rate network I/O has. That's not entirely true. Delphi's GUI model is event-driven so I'm willing to bet ANY call to Application.ProcessMessages will be made as a result of handling an message or event. And I'm willing to bet most calls to Application.ProcessMessages can be traced to ether an TButton.OnClick event or a menu item's OnClick! And if it's such a big issue for ICS, why isn't there a simple 5-line-of-code test that would raise an exception if any code is re-entered? Why ? It is correct that it should enter that event. Incorrect use of processmessage lead to the incorrect moment of entry! Besides, I'm asking about such behavior because of the way the THttpCli component behaves for me. If you remember one of my earlier questions, I had lots of problems with the component failing to connect to my HTTP server. Using Ethereal I determined the connection is poor (lost packets, duplicate ACK's) BUT the component still averages an too high number of failed connections. I don't think I've had 5 consecutive sessions where no connections timed-out. And I'm saying the failure rate is too high because I never saw such a problem using my web browser. Not once! And after the time out expires and the component aborts and restarts it's Get, it usually finishes very very quickly. So I need to ask: Is there some other obvious thing I'm missing, like a call to Application.ProcessMessage? What else should I be looking for. So did you trace you browser then ? My gues is that there are as many failures but they are handled by the browser. You could do that as well in you application.

They all use the same component and no exception is raised. I put socketspy between the proxy and the web server and the data reaches the web proxy however what I could figure out from the delphi code is that the state of the component is httpwaitingheader after the HEAD whereas it ought to be httpReady.

Arno,
I tested this url and your change (only GetHeaderLineNext) and yes with
connection keep-alive of no setting on connection all is fine. However
with connection set to close the relocation fails on the third one. If I
try to find where it hangs it shows
DoRequestSync
Application.ProcessMessages
with fstate = httpwaitingbody.

Since I've never been using THttpCli in one of my applications I'm
not very familiar with HTTP as well as the THttpCli. That's why I
wonder whether it is intented to trigger RequestDone on each
relocation or not (sometimes it's triggered in V5, V6 sometimesnot),
probably someone more familiar with the component can clear me up?
With two simple changes I can make the FollowRelocation feature
working for the problem URL of the OP, however w/o RequestDone being
triggered on relocation.

[twsocket] ICS V6 Http Post problem
Already asked this in the borland newsgroup but was advised to asked it here again. I use v6 latest beta and if I do a asyncpost wiht some long parameters like Para1= para2=b para3=..(about 1600 chars) I will see something else with a sniffer Para1= para2=b para3=..( only a part of them) Para1= para2=b para3=..(again a part of them) Anyone with a hint how to solve this.?
