The notes() method can be used to make various Apache modules talk to each other. In the following snippet the PHP module talks to the mod_perl code (PHP code): if (isset($user) && substr($user,0,1) == "+" { apache_note("user", substr($user,1)); virtual("/internal/getquota" $quota = apache_note("quota" $usage_pp = apache

Unless you use some well known module like CGI::Cookie or Apache::Cookie, you need to handle cookies yourself. Cookies come in the $ENV{HTTP_COOKIE} variable. You can print the raw cookie string as $ENV{HTTP_COOKIE}. Here is a fairly well-known bit of code to take cookie values and put them into a hash: sub get_cookies { # cookies are separated by a semicolon and a space, this wil

I wrote this script a long time ago, when I had to debug my CGI scripts but didn't have access to the error_log file. I asked the admin to install this script and have used it happily since then. If your scripts are running on these 'Get-free-site' servers, and you cannot debug your script because you can't telnet to the server or can't see the error_log, you can ask your sysadmin to install t

Under mod_cgi it's not easy to redirect POST requests to some other location. With mod_perl you can easily redirect POST requests. All you have to do is read in the content, set the method to GET, populate args() with the content to be forwarded and finally do the redirect: use Apache::Constants qw(M_GET); my $r = shift; my $content = $r->content; $r->method("GET" $

What happens if you need to access the POSTed data more than once, say to reuse it in subsequent handlers of the same request? POSTed data comes directly from the socket, and at the low level data can only be read from a socket once. So you have to store it to make it available for reuse. There is an experimental option for Makefile.PL called PERL_STASH_POST_DATA. If you turn it on, you can ge

Many error conditions result in an exception (or signal -- same thing) which is raised in order to tell the operating system that a condition has arisen which needs more urgent attention than can be given by other means. One of the most familiar ways of raising a signal is to hit Ctrl-C on your terminal's keyboard. The signal interrupts the processor. In the case of Ctrl-C the INT signal is gener

The Apache::Request module gives you an easy way to get form content, including uploaded files. In order to add file upload functionality to your form, you need to add two things.
