I recently updated my Linux/Apache/MP2 environment, in part hoping to resolve a problem that occurs with about 10% of my clients. These clients experience a timeout from my server when they submit a form using POST having more than about 15KB of data (from httpd access_log -- the actual posted data may be much less than this). I think it is related to their proxy/firewall as the same computers/users do not have the problem when they connect directly to the Internet (i.e. dial up) to access the same form pages.
I can replicate the problem using a very basic CGI form. It uses CGI.pm and is hanging on the line "my $q = new CGI;" when the POSTed data exceeds the 15KB threshold from these clients. The httpd access_log shows an error 500, and the httpd error_log shows the following, [Wed May 17 20:17:47 2006] [error] Apache2::RequestIO::read: (70007) The timeout specified has expired at (eval 178) line 5 Even if the problem is originating with these clients' proxy/firewall, it should never result the timeout/hanging of the CGI.pm. Does anyone have a suggestion on how to trace this or trouble-shoot it further? Apache/httpd 2.2.2 Mod_Perl 2.0.2 (problem occurs with/without mod_perl) CGI.pm 3.20 Apache2::RequestIO 2.000002 Linux FC3: 2.6.12-1.1381_FC3smp Perl 5.8.5 Client: IE6 One client's proxy sets environment variable HTTP_VIA="1.0 WEBSENSE01SA, 1.0 Symantec_Web_Security (3.0.0.52)" Any suggestions/experience would be greatly appreciated, Tom __________________________________________________ Do You Yahoo!?
