Apache2::Request->param fails with POST

Hi I am using Apache2.2 and mod_perl. I have a login page that POSTs to an
authentication script.
<form method=POST
action="/authenticate?sid=06eff4cdc3231db0236cdbe2c51e6618">
<table>
<tr>
<td align=right>User(or email): </td>
<td><input type=text name=email value=""></td></tr>
<tr>
<td align=right>Password: </td>
<td><input type=password name=password></td></tr></table>
<input type=submit value=Login><BR>
</form>

on the server side.. I have the following code...

use Apache2::Request;
use Apache2::SubRequest;
use Apache2::RequestRec ();
use Apache2::Upload;
use Apache2::URI;

my $r = shift;
my $req = Apache2::Request->new($r);

#Get the Query String and POST data
log("PROCESS", "MESSAGE", "Inside");
my @keys = $req->param;
log("PROCESS", "PARAMS", Dumper($req->param));

when I post the form, the logs show till "Inside" and the browser keeps
loading the page, the CPU consumption on the server is 100% by httpd.

however, if I change the form so it uses GET instead of POST, everything
works fine.

Any help is appreciated.

thanks
Nishant

Obviously that shouldn't happen. Is there anything in the error log?
What version of apreq are you using?

thanks for your reply Adam
There is nothing in the error logs.
I think the version is 3.7.1 (/usr/lib64/libapreq2.so.3.7.1)

could this be a result of virtual hosts?

Try not mixing GET and POST parameters. Put that sid as a hidden input
in the form instead of a GET parameter on the query string? Technically
you're not supposed to mix the 2, but most systems allow it anyways. But
maybe it's tickling a bug here.

Re: Apache2::Request->param fails with POST [In reply to]

I have tried that but it still doesnt work. I even tried to POST an empty
form (with no GET or POST params) with same results

Re: Apache2::Request->param fails with POST [In reply to]

It seems like your libapreq install is broken or something. Did it pass
all the tests when you built it?

Re: Apache2::Request->param fails with POST [In reply to]

This may be obvious, however note that calling $req->param will invoke
the input filters, should have have any configured.
