[SOT] Strange browser behavior
I am using a mod_perl content handler to implement a series of forms. The first request from a particular browser is always a GET that provides some required parameters in the URL. From then on, all parameters are passed as hidden form variables, and only POSTs should occur. If the browser accepts cookies, a unique session ID is stored in a long lived cookie and is also logged in the access log, strictly for tracking (no session data associated with it). This is not 100% reliable because not everyone accepts cookies, but it works enough of the time that I can track most of the requests by this ID. 99.9% (roughly) of the time, everything works fine and the correct sequence is followed: GET /formseries?a=123b=234 POST /formseries (a=123, b=234 passed in post vars) POST /formseries (a=123, b=234 passed in post vars) POST /formseries (a=123, b=234 passed in post vars) POST /formseries (a=123, b=234 passed in post vars) POST /formseries (a=123, b=234 passed in post vars) The problem is that there are a few request trails per day, where the following sequence is followed instead: GET /formseries?a=123b=234 POST /formseries(a=123, b=234 passed in post vars) POST /formseries(a=123, b=234 passed in post vars) POST /formseries(a=123, b=234 passed in post vars) GET /formseries (required parameters not passed on this request) The GET fails because the handler does not have the required parameters it needs to pull info from the database. An incomplete of user agents that the problem occurs with are: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt) Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0) Mozilla/4.0 (compatible; MSIE 5.5; Windows 98; Win 9x 4.90) One other piece of evidence is that the Referer is empty on the erroneous GET request. I have tried but been unable to reproduce the failing request sequence using IE, even using back, forward, and reload button in a number of sequences. My questions are, is there some IE anomaly or some anomalous way of configuring or using IE that can cause it to all of a sudden do a GET instead of a POST (anything short of manually entering the url)? Could a proxy be causing the problem (a small subset of the failing requests to seem to be coming through proxies)? Also, is there anything more I could track that would give more insight into the problem? Currently the content handler does detect that the required parms are missing and then dumps the complete request and timestamp into the error log. Also, please let me know if there is a more appropriate forum to ask this question. -- Matthew Pressly

Hi Treveor, I've seen three fixes to this sort of problem in the past, so you might want to see if any of the following apply to your case: 1) Changing Browser - Galeon had me testing for days, when I could clearly see that I was getting the correct header, via telnet to the port. See below. 2) Turning PerlSendHeader Off and sending your own headers. The problem was probably somewhere else, but sending my own headers fixed it. Then again, the problem might not have been elsewhere. 3) Make sure you're not sending your header twice. With PerlSendHeader being on or off, plus a code segment sending a header/or some gibber elsewhere, or even a stray 'print' to STDOUT from some other place, before the header is dispatched. I've had header trouble a couple of time and have often found telneting to the vhost to be a very handy detector of what might be going wrong. If that fails then paracetamol is usually a good cure.

Both the cases above may be ocurring to some degree. A segment looks like it may also be caused by proxies. Browser caching may also be causing some of it, and there may be other causes as well. Setting $r-no_cache(1) did not solve the problem, though there is a chance it may have alleviated it somewhat.. Since there is a session id generated for browsers that have cookies enabled, I'm planning to stow away the parameters in either the database or File::Cache on the first GET request when parameters are available, then fall back to looking there on subsequent requests if and only if the parameters are missing (not in query string and not in POST data). This should fix most of the currently failing cases without much more code. Thank you all for your help. -- Matthew Pressly
Re: problems with characters being added to a request.
Okay, I've been able to create a simple testcase that reproduces the
problem I'm having. Hopefully some perl/mod_perl guru out there will be
able to tell me what the deal is. The program basically print out
three strings, concatinates a few strings and print them out too. I've
attached two files, the handler, and the output of a page it created.
Any help would really be appreciated.

getting printed, and when the variable is sent to STDERR r 222 is
getting sent. I get the added character with IE, Netscape, telnet
localhost 80 and wget. So i don't think it with the browser.

I agree, it is a great book and I spent quite some time reading it before asking the question. Unfortunately, either I have missed something in the book or you've misunderstood my question. What I want to do is determine the current setting of the standard 'DirectoryIndex' parameter used by mod_dir. This is not a simple PerlSetVar and it is not a new directive I'm creating for my Perl module - both these scenarios are covered in book. What I want to know is, for the current Directory/VirtualHost/Server, what would mod_dir do? Regards Grant
Re: am i heading for disaster... ?
I definitely didn't run out of disk space, so it must have been something
else. There were a number of funky things that happened over the course of
the build. The first time around, I made mod_perl, then made mod_ssl, and
had an error about util.o being out of sync with mod_ssl, so then I ran the
mod_perl make a second time, without cleaning first. Maybe the file got
erased in the process. The next time I ran apache make, I had a linker
error and had to set LD_LIBRARY_PATH explicitly to correct it. Maybe I
needed to do the same while building mod_perl.
But, knock on wood, the server hasn't choked yet, or behaved weirdly. Guess
I'll find out when it goes into production...
Thanks

UltraSparc, with Perl 5.8, the apache make failed because of an

then build mod_perl, then configure apache, loading mod_perl statically.
Anyway, I poked around and found that indeed the uri_delims.h file in

Then when I ran make again, everything was hunky-dory. Now what I want
to know is, why would this have happened in the first place? Is it a
sign that something is fundamentally wrong with the build, but I just
haven't seen it yet? Or should I just breathe easy and hope for the
best?
I doubt this has anything to do with mod_perl. The build hasn't changed
in years, so it must be some external glitch. For example you might have
run out of disk space, so when it was writing the file it was zeroed.

Re: Accessing configuration information

This is described in the [EagleBook] (worth your money, IMHO), and this particular chapter is available on-line: Thanks for your reply. I agree, it is a great book and I spent quite some time reading it before asking the question. Unfortunately, either I have missed something in the book or you've misunderstood my question. What I want to do is determine the current setting of the standard 'DirectoryIndex' parameter used by mod_dir. This is not a simple PerlSetVar and it is not a new directive I'm creating for my Perl module - both these scenarios are covered in book. What I want to know is, for the current Directory/VirtualHost/Server, what would mod_dir do? you have very few options here. one of which is to do Perl $Apache::Server::SaveConfig = 1; $DirectoryIndex = 'index.html'; /Perl then you can access the variable in your script as $Apache::ReadConfig::DirectoryIndex you can also use directive handlers to override the DirectoryIndex directive and stash it someplace you know about. an example of how that can be accomplished is here: http://www.modperlcookbook.org/code/ch14/Cookbook-MIMEMapper-0.01.tar.gz the last resort is to plug right into mod_dir's private data. you can find an example of that kind of thing here: http://www.modperlcookbook.org/code/ch08/Cookbook-LanguagePriority-0.01.tar.gz HTH --Geoff

state of the art throttling?
What is the state of the art now in apache or modperl related modules that will throttle based on a combination of the following metrics: * recent bandwidth per IP * recent request count per IP * max number of parallel requests per IP I'm using a tweaked version of the Stonehenge utility and it works ok but a bad robot (and there are SO many now) can fill all request slots before a long enough measurement period has elapsed to start denying it service.. plus the process of denial is not insignificant because the recent request record has to be opened and summed for each new request.. ideally the IP or IP+ua combination should be just bounced out for a defined period of time to cool off. Also this mystical throttle module I'm hoping exists would sit at the front end, along with mod_rewrite, rather than be installed on multiple back end modperl servers.. Something that crawled the apache status tree to deny requests when more than N servers are already engaged in serving the same IP, would be ideal.. Since I offload image serving, I think this would not hurt any legit users. thanks! -Justin

Re: Problem with Stream-oriented Output Filter
Esteban Fernandez Stafford wrote:
Hello,
I am currently developing a modperl filter that uses the streaming
approach. I started off with the example in
http://perl.apache.org/docs/2.0/user/handlers/filters.html#Stream_oriented_Output_Filter
sub handler {
my $filter = shift;
my $left_over = '';
while ($filter-read(my $buffer, BUFF_LEN)) {
$buffer = $left_over . $buffer;
$left_over = '';
while ($buffer =~ /([^\r\n]*)([\r\n]*)/g) {
$left_over = $1, last unless $2;
$filter-print(scalar(reverse $1), $2);
}
}
$filter-print(scalar reverse $left_over) if length $left_over;
Apache::OK;
}
This seems to work OK when the file is small (smaller than 8192). When
the file is larger, then there is a line that gets cut. This is
because the handler gets called more than once for big requests. Is
there a nice way to overcome this problem? I was thinking using
filter context to store variable $left_over, but then I dont know how
to detect the real end of the stream.
The problem is that I've written a patch that makes the $filter-print()
outside the while() loop work, but it was never committed. So the doc
is out of sync with the core code. For now please apply this patch:
http://marc.theaimsgroup.com/?l=apache-modperl-devm=102828686110352w=2
I'll see that it gets into the core asap.

PATCH: Apache::AuthDBI
I have been having trouble connecting to my user database, according to the logs,
there was never any password returned.
After browsing through the code, I found the following:
---start code---
undef $passwd if 0 == $sth-rows; # so we can distinguish later on between no password
and empty password
---start code---
According to the DBI documentation here:
http://search.cpan.org/author/TIMB/DBI-1.30/DBI.pm#rows
---start quote---
So use of the rows method or $DBI::rows with SELECT statements is not recommended.
---end quote---
It seems my particular driver (PgPP) is returning a 0 to $sth-rows, which undefs
$passwd, even if there was a password returned.
So I cooked up a patch to fix it. (Attached)
It simply increments a counter while looping through the recordsets and checks that
counter instead $sth-rows.

Re: mod_Perl script and SSI need advice

I'm afraid I don't quite understand your description

it that the SSI is not working, or that the CGI
isn't getting the right
input, or what? Can you show us some of the code
from the HTML page
and the CGI script? How are you running the CGI?
Apache::Registry?
- Perrin
Here is an example of what I mean:
Here is a basic form built with cgi.pm.
Name the script test
print header;
if (param(foo)) {
print start_html,
You Entered: ,em(param(foo)),
}
else {
print start_html,
start_form(-action=/perl/test),
Enter something : ,textfield(foo),
submit,
end_form,
}
print end_html;
Works with no errors under CGI and Apache::Registry
Then I would add the above script as an include in the
following page (demo.shtml):
html
head
titleTest SSI Page/title
/head
body
pThis is a test page/pbr
!--#include virtual=/perl/test --
/body
/html
So the when I access demo.shtml, I see the text from
the HTML page and also the form from the included
scipt.
When I fill out the form and hit submit, the returned
data gets printed to the screen:
You Entered plus whatever you entered in the form.
What I would like to do is fill out the form, submit
it, and end up back to the shtml page with the result
of the script (rather than the form) included in the
shtml.
I understand why this is happening, I am not asking
why, all I am asking is what is the preferred method
of accomplishing this.
