[twsocket] Update the browse
I just started to use ICS components and they appear very simple to use and powerfull, the sample help a lot for me that have a small knowlegment in HTTP protocol. I built a HTTP server using the ISC HTTPSever component and I have a question, I need update the browse by the server side without the browse send a request to me Is it possible? If yes how can I do this?

Re: [twsocket] Update the browse
I built a HTTP server using the ISC HTTPSever component and I have a question, I need update the browse by the server side without the browse send a request to me Is it possible? If yes how can I do this? Technically, it is possible except the HTTP protocol has no provison for doing that. Usially, it is done using differents ways: 1) The browser request a periodic refresh because he received a HTML document containing the line: META HTTP-EQUIV=Refresh CONTENT=2;URL=mydocument.html The number 2 above is the number of seconds the browse wait before requesting the given URL. 2) The server reply to some normal request with a never ending document. You either omit Conten-Length or use a huge value. Most browser analyse received document on the fly and display as it comes in. 3) Use a Java Applet or ActiveX object that establish a secondary connection to your server and do whatever they like with that connection. -- [EMAIL PROTECTED] http://www.overbyte.be -- 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
[twsocket] Twsocketserver
Hi guys, I do have a realtime application communicates to one side by USB and to the other acts as http server and/or TCPserver. I am trying to use ICS http server and everything seems OK. I use another free component of TCP server that has to run in different thread because of not event driven. Synchronizing makes me a lot of problems so I decided to use TCP server from ICS. My TCP communication isn't line oriented. Could I find any documentation to Twsocketserver or some example how to handle binary and maybe fragmented packets? I am already late with my project so I would prefer quick, maybe dirty help :-( Thanks in advance Igor -- 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 content encoding

I hope other people will partecipate to this discussion. a) Isn't it possible to defer call to THttpContentCoding.GetCoding until it is really needed so that exceptions are raise at that time ? I made some changes, now the GetCoding is called only when it is needed. b.1) There is already a property Options which is a set of properties. It is better to extent this set. First, I mention record but I mean object. Usually I don't use anymore a set for a property mainly for two reasons. The first is that set are limited in the number of members. The second, and more important for me, is that sets doesn't works well with VFI, because you cannot switch a member without affecting the others. But last word is yours. b.2) No opinion now. I decided that disabling mean that the whole things is not handled by the component (like today). c) Acceptable. Maybe add an event with a boolean var argument ignore. If ignore is true, nothing special happend, the document is receive undecompressed. If ignore = false then an exception is raised. Just an idea. I'm not convinced. We should think about a real scenario. I think that it is better for the moment that it remain as is, and then make a change when/if it is real needed to handle a real situation. Opinion from others reader? d) I do not master the topic. Could you elaborate ? I know only what I red from RFC. This is what I understood. You can specify in the header what kind of encoding you can handle. This doesn't mean that you cannot receive a body encoded with a method not included in the Accept-Encoding. A second form is to specify the econding with a quality parameter, for example gzip:1 deflate:0.9. With this you inform the server that you can handle both gzip and deflate but you prefer gzip. If you specify 0 as quality then it mean that you don't accept the encoding. Two particular encoding are identity and *. You will never see this in the answer, only in the Accept-Encoding header. The first mean no encoding and the second all others. So if you write gzip:1 identity:0.2 *:0 should mean I prefer gzip over identity, but doesn't accept any other encoding. Even this should be possible: gzip:1 identity:0 *:0 i.e. send me only encoded with gzip. This is the theory. Practically I made some test with IIS 5.1 and it seems ignore completly the quality. Actually I made some changes to disable the quality by default and use 0 as default quality for indentity and *. Coding with quality = 0 will not specified in Accept-Encoding if quality is not used.

Re: [twsocket] Twsocketserver
You could use a custom small header on every packet you send, i.e. first 2-4 bytes being the packet size, so when you receive data you add to a buffer and check if it reached the total size of the packet. If it has not, do nothing, if it has, complete the buffer and send the data packet to a processing routine. If the last data amount received exceeds the packet lenght you specified in the header, you can cut it and move it into a new clean buffer. I have some sources for that if you need - Original Message - From: Igor Pokorny [EMAIL PROTECTED] To: twsocket@elists.org Sent: Monday, August 15, 2005 00:50 Subject: [twsocket] Twsocketserver Hi guys, I do have a realtime application communicates to one side by USB and to the other acts as http server and/or TCPserver.
