That's not true at all. Google for "cgi post vs get", or see get vs post .So you can post to a script in any language. The thing about a post, is that it contains a message body after the header, usually a file encoded for upload. Now, the rumor you heard that only a .pl file can accept a post, is just confusion over how the web server is setup. You can configure a web server, so that perl scripts must end in .pl, but it is not a hard-and-fast rule, some servers are setup so that scripts must end in .cgi. Basically, a GET request contains all information in the url string that is sent, while a POST sends a url string, followed by a block of encoded information, which is usually the file.

Now a script can be written to NOT allow posts, as a security measure, so that may be the source of your first error. If a script does allow posts. it needs permissions to write the file on the server. Usually you need to write to a directory with 777 permissions, since a webserver usually runs with the lowest of permission levels, like "user:nobody, group:nobody".

You can test posting with this script, which will print out whatever you post to it. Name it showpost.cgi or showpost.pl

#!/usr/bin/perl  -wT
use strict;

my $buffer;
read (STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
print "Content-type: text/plain\n\n";
