Re: problems with sessions and upgrading
hi perrin, yes, i did read the discussion with interest a few months back regarding what should be stored in a session and what in the back end database. customer and order data is properly stored in a secured back end system. the cart contains data that i want to keep for 30 days, such as cart data, affiliate reference data and things of that nature. i have found the sessions to be simple, quick, convenient and a reliable way to maintain this transient data. the fact is, the data is in there, and i need to migrate it to the new sessions. i may redesign the system at a later time, but the buying season is upon us, and reenginerring this part of the system is not in the current plans. thanks! cliff [EMAIL PROTECTED] wrote: Frankly, this all begs the question of why you are putting important long-term data in Apache::Session.

ok - here is something ugly - off the top of my head. when a user submits without a cookie, or a cookie that u do not recognize: 1) Set-Cookie for the proper domain (i.e. .rhythym.com) 2) redirect them to the requested page, but with a fully qualified host/domain (i.e. http://www.rhythym.com/someLocation/) Rasoul Hajikhani wrote: Hello folks, Yesterday I posted a question about PerlTransHandler and received a lot of responses. Thanks to all of you who replied. However, my problem persists. I try to be more precise in explaining the problem today. My login module sets a few cookies that expire 24 hrs after they are set. Upon each request the validity of the cookies is checked, and in case of an expired cookie, the user is redirected to the login page to resubmit username/password again. A request with a fully qualified URL, example: http://myserver.mydomain.com/someLocation, has no problem continuing. The cookies are set. However, in case the URL has the .domain.com stripped, the login page is regenerated indefinitely. The cookies never get set. There were a few suggestions, such as using mod_rewrite, however that is out of the question because mod_rewrite was not built with our http server. My PerlTransHandler does not seem to be able to distinguish myserver.domain.com/someLocation request with myserver/someLocation.

Re: Thanks and GoodBye
i have a set of detailed plans that allows for a mod_ssl front end with mutliple backends, of which i have built mod_perl and mod_php. this version works in a virtualhost environment (i did not setup the php for virtualhost, but that is trivial). it has not yet been tested in a heavy production environment, but it should build just fine, and it will work great for testing and learning. i think it will work better on 1.3.24 (because of better proxy buffering and releasing), but there was a bug in that release, and the patch came out after i reverted to 1.3.23. let me know if you'd like a copy. cliff John Kolvereid wrote: Hi Perrin, I might try it later.

proxy front to modperl back with 1.3.24
i had trouble using a proxy front end to both a mod_perl and mod_php back end servers. this works fine for me at 1.3.23, so I reverted back to it. i copied the httpd.conf files from the 1.3.24 to my downgraded 1.3.23 and everything worked correctly on the first try. i was getting garbage characters before the first html or doctype tag, and a 0 character at the end. also, there was a delay before the connection would close. i tried turning keep alives off and on in the back end server, but i did not note a change in behavior i also tried some different buffer directives, including the new ProxyIOBufferSize. these garbage characters and delays were not present serving static content from the front end server, or when directly requesting content directly from either of the back end servers. i know they've made some mods to the proxy module, including support for HTTP/1.1, but i did not have time to research the exact cause of the problem. just a word of warning before someone spends hours in frustration, or perhaps someone can give me a tip if they've solved this problem. -- ___cliff [EMAIL PROTECTED]http://www.genwax.com/

Re: AddModule mod_perl.c

Re: How to get two perl namespaces in apache
Thomas K. Burkholder wrote: run them in two different environments - I don't think running them on two different virtual servers is going to do it, right? Doesn't apache just start one perl runtime? Please tell me if I'm mistaken about there is only one interpreter, so running a module with the same name on two different virtual servers is not going to work. So, I guess I'm wondering if there's an easy way to have two completely separate apache configurations running on the same machine (listening on different ports obviously). sure. just leave the regular config file, then build something like: httpd_dev.conf change both the Listen and Port directives to an alternate port, and then start with: httpd -c httpd_dev.conf i haven't tried this exact scenario myself, but it should work without a problem. -- ___cliff [EMAIL PROTECTED]http://www.genwax.com/
Re: [OT-ish] Session refresh philosophy
Rob Nagler wrote: [EMAIL PROTECTED] writes: Looking at CGI::EncryptForm that Perrin mentioned, it appears that that module would address this concern by storing client-side in a single encrypted string that gets put in one hidden form variable. That also avoids having to verify more than once. It is always good to validate the data even if it was encrypted. It is also generally a good idea not to give the user any secrets, even if they are encrypted. In other words, avoid trusting the user. [EMAIL PROTECTED] writes: No, this just means that input must be validated once again when the last «really, really sure ?» button is depressed. Conceptually, this divides the pages of your site into two categories (not unlike the view vs. controller distinction in Model-View-Controller paradigm for GUIs): those that just interact with the user and do the navigation, and those that actually have side effects such as writing data into your database, sending e-mails, placing orders etc. It is MVC. However, instead of thinking of pages, I like to think in terms of tasks. The same task that renders the form also validates and executes it. In the case of execution, the result is a redirect described by the site's state machine. A form in our world has four states: execute_empty (fill in defaults), execute_ok, execute_other (e.g., cancel or sub form), and execute_unwind (coming back from a sub form). All of these paths go through the same task. please take this as interested and not critical. i was viewing the source: http://petshop.bivio.biz/src?s=View.items and i noticed these lines: - snip ])-put( cellpadding = 2, cellspacing = 2, ), - snip - this looks like the presentation layer peeking through. the petshop site is obviously a demo, and therefore does not have the polished look of a professional site, which is very understandable. what i wonder is, could a professional web design team make a polished website without involving the programmers? what happens when a cell padding of 3 is more desirable for the design? it seems to me, that in all of the technologies i have looked at thus far, that attempt to separate the presentation layer from the model/view, the precision and flexibility needed to graphically communicate to the user is more difficult that the standard pagedesign approaches (dreamweaver and a little embperl or other embedded language thrown into the mix) . phrased another way, how does bivio or other mvc technology, let web artists design sites as beautiful as http://www.marthastewart.com or the even more beautiful http://www.genwax.com (cheap plug)? -- ___cliff [EMAIL PROTECTED]http://www.genwax.com/

remember, computers are binary machines. your 323.82

using binary math. when you scaled it four places to the left,
you saw the results of the approximation. FreeBSD appears
more accurate on this particular calculation, but it might
be less so with different input.
check out one of the Math:: packages on CPAN,
you should be able to find something that will give you the
accuracy required for your application.

It seems that I had explained my intention not enough in last mail. I had written the patch to solve following problem. (1) Since perl_merge_dir_config() uses ap_overlay_tables() to merge PerlSetEnv variables, overridden variables remains in the table as association list elements (internal representation of Apache's table). (2) The table remains precedences and consistency kept while manipulated by Apache's standard table APIs (e.g. ap_table_get()). (3) Although (2), mod_perl scans through internal structure of the table directly as association list to dumps variables into %ENV by mod_perl_dir_env(). This causes precedence reversed on dumped %ENV variables because the list elements is ordered by descending precedence. Above process results that PerlSetEnv always activates least specific Directory section value. It's a real bug. My patch modifies (3) by reverses iterating direction on dump. I would like the patch to be tested by someone else and included in the mod_perl distribution. Please help!

Re: URI::URL - problem
i got this to work. my method is ugly. i noticed everywhere that
URI::URL was being used in mod_perl and embperl, LWP::UserAgent
was being used.
also, i found this is the LWP (libwww-perl-5.5395) release notes:
HTTP::Request, HTTP::Response will by default now use URI class,
instead of URI::URL, when constructing its URI objects. This
has a potential for breaking existing code as URI::URL objects had
some extra methods that external code might depend upon.
so - i performed this patch in (perlsitelib)/(perlversion)/LWP:

Re: Appending Sessionid to all the urls
i'd still use a cookie to indentify the user. why not include
the client id as part of the submission from the browser. it
is easy to keep detailed data in the cookie separate for each client
$sessionData{$clientKey}{$clientDataStuff}=$in{DATAKEY}
Stuart Frew wrote:
This is an even more pronounced problem with sessions IDs in
URLs, though. With cookie based session tracking, the second
browser window will send the same cookie that the first browser
window received.
And there lies the rub.
The user is using the system to process client A. The cookie contains
stateful information including the client ID.
They then open an new browser window, and lookup client B, recieving a
new session ID with new state information, including the client ID.
The user then submits the form to the server.

yes. this method assumes that the administrator of apache has made
a change to a file and now wants to reload it. this is how some unix
services work such as named and inetd. you modify the config

This one cost me about a week, so don't feel too bad! if someone enters our site with domain.tld (no hostname), everything works fine as long as they keep using relative links. as soon as they select or get redirected to an absolute link (usually when changing schemes http = https), then the domain of the cookie fails, and the cookie data is lost (as far as the browser is concerned). this problem is avoidable if u insure that a proper hostname is used along with a domain.tld. i do this with mod_rewrite. there are probably many ways to do it, but the effect is the same, insure that the cookie domain matches through the user's entire session. someone suggested using the apache directive canonical hostname. my canonical hostname does not always match the host and domain.tld of my server. if it does, then this directive will probably eliminate the no hostname cookie domain matching problem (a technical term ;-) ). -- ___cliff [EMAIL PROTECTED]http://www.genwax.com/

On a side note, I'm curious about is how Apache decides that child
processes are unused and can be killed off. The spawning of new processes
is pretty agressive on a busy server, but if the server reaches a steady
state and some processes aren't needed they should be killed off. Maybe
no one has bothered to make that part very efficient since in normal

Re: killing of greater than MaxSpareServers
if you are able to determine how much core memory is left, you may also be able to determine average apache process size and variance. then, apache can determine whether or not to start up any additional children. i'm not sure how much processor time would be taken to determine free core memory. might not be something worth doing on every scoreboard cycle. there is an additional bonus for determining child size mean and variance. if it is noted that a process is growing exceptionally large compared to other processes, it could be slated for death based on its growth size and rate, rather than the number of requests that it served.

Otherwise, it has no way of knowing whether or not there's enough room for another process. A combination of Apache::SizeLimit and a dynamically changing MaxClients could possibly accomplish this, but you wouldn't want to run it too close to the edge since you don't want to have to axe a process that's in the middle of doing something just because it got a little too big (i.e. no hard limits on per-process memory usage).

Re: the edge of chaos
i see 2 things here, classic queing problem, and the fact that swapping to disk is 1000's of times slower than serving from ram. if you receive 100 requests per second but only have the ram to serve 99, then swapping to disc occurs which slows down the entire system. the next second comes and 100 new requests come in, plus the 1 you had in the queue that did not get serviced in the previous second. after a little while, your memory requirements start to soar, lots of swapping is occuring, and requests are coming in at a higher rate than can be serviced by an ever slowing machine. this leads to a rapid downward spiral. you must have enough ram to service all the apache processes that are allowed to run at one time. its been my experience that once swapping starts to occur, the whole thing is going to spiral downward very quickly. you either need to add more ram, to service that amount of apache processes that need to be running simultaneously, or you need to reduce MaxClients and let apache turn away requests. -- ___cliff [EMAIL PROTECTED]http://www.genwax.com/ P.S. used your service several times with good results!

Re: PerlRun StatInc perl5_00405
here is something that occurred to me, but it is untested, and could be
plain foolish.
place a file named warnings.pm in your 5_00405 include path that contains the
infamous:

this may help to quiet StatInc.
Chris Strom wrote:
No, I don't have warnings.pm. It is only included in 5.6. We have no plans

causing problems with StatInc.
perl -V reports:
Summary of my perl5 (5.0 patchlevel 4 subversion 5) configuration:
It may be that the combination of PerlRun/StatInc/perl5.6 simply will not
work. If we were not using StatInc or were using perl 5.6, I do not believe
that we would be having these problems. Unfortunately, our development
environment would be rather painful without StatInc and, as I said, we have
no plans on upgrading from 5_00405.
For now, I've got the following hack in perl.conf:
PerlModule Apache::StatINC
#
# hack to keep $INC{'warnings.pm'} defined. PerlRun includes a
# workaround for perl5.6 which defines $INC{'warnings.pm'} and
# ties the warnings::unimport function to an anonymous sub-routine.
#
PerlInitHandler "sub {delete $INC{'warnings.pm'};
$INC{'warnings.pm'='/usr/local/lib/perl/site_perl/Apache/PerlRun.pm';}"
PerlInitHandler Apache::StatINC
PerlSetVar StatINC_UndefOnReload On
PerlSetVar StatINC_Debug 1
PerlWarn On

Do you even have the file 'warnings.pm' if you're using 5.004_05?
I have it in a 5.6.0 inststallation, but not in 5.005_03. That's

sorry, but i fail to see why all the trickery is needed. i assume that
you want to check the content against what is expected, but the banners
are rotating based on some formula. if you know the formula before hand,
then you know the expected distribution for the banners served. why not
use something from libwww package to make the requests, md5 the returned
banner relavant data, return a report which gives the counts for each unique md5.
so in perl pseudocode (untested, no error checking, steps skipped):
for $testnum (0..$number_to_test) {
$request_url=@bannerurls[rand(@bannerurls)];
$req = HTTP::Request-new(GET = $request_url);
$res=$ua-request($req);
if($res-is_success){
$dig=md5($res-content);
$md5{$dig}++;
}
$md5{__ERROR__}++;
}
}
foreach $dig (keys %md5){
print "the banner with digest=$dig returned $md5{$dig} hits
for",($md5{$dig}/$number_to_test)*100),"% of total\n";
}
the report should print the distribution requested. not sure if this can be done
using ab or the bench
i believe Stas was working on, but libwww is easy to use. you can even distribute
this test to a few
of your friends and have them bang on your system from a variety of different places
to test your
system in a more realistic environment. then write a program to scour the logs for
the test period,
and produce the same report from the logs. they should match almost exactly. only
differences in
incompleted log requests etc..
1) Is there a more elegant way of solving my problem?
2) Has this been done before?
2a) If so, is the source for that available?
2b) If not, is a tool like this useful for anyone else,
so that I should build it better than I would a once-off?
What would make it more useful?

Re: Apache trouble reading in large cookie contents
i'm not an expert with this, but, a quick grep for your error in the apache source (mine is still 1.3.9 ) and some digging yield: ./include/httpd.h:#define DEFAULT_LIMIT_REQUEST_FIELDSIZE 8190 so you're right, 8K is currently the apache limit. if you try to change this value in the source code, you will probably also have to muck with IOBUFSIZE and possibly other things as well. IOBUFSIZE is 8192 and the DEFAULT_LIMIT_REQUEST_FIELDSIZE is set to 2 bytes below that to make room for the extra \r\n after the last header. looks like you'll have to take responsibility for mucking with the apache source, or sending smaller cookies and using some other techniques such as HIDDEN fields. -- ___cliff [EMAIL PROTECTED]http://www.genwax.com/ "Biggs, Jody" wrote: I'm having trouble when a browser sends a fair sized amount of data to Apache as cookies - say around 8k.
