Re: [users@httpd] Apache cgid:error for HTML::Template::Pro templates larger than 8k
or in HTML::Template::Pro and both mod_cgid/mod_cgi have an issue with it at 8k/4k.

Can you capture the output of the CGI process run under httpd at least up to the point of the !doctype html text? I'd guess you are suffering from buffering somehow, and the threshhold is a different value with mod_cgid vs mod_cgi. -- Born in Roswell... married an alien... http://emptyhammock.com/
[users@httpd] Apache cgid:error for HTML::Template::Pro templates larger than 8k
My web server: FreeBSD 10.0, Apache 2.4, Perl 5.16, HTML::Template::Pro 0.9510 When I try to run any perl script calling HTML::Template::Pro templates larger than 8,191 bytes, I get following error in httpd: [cgid:error] malformed header from script 'test.pl': Bad header: !doctype html Running the script from command line (even with template files of several MBs in size) produces the expected output and no error, so I am suspecting that the cause of the error is related to Apache. Here is the simple perl script 'test.pl' that I tested with: #!/usr/bin/perl use strict; use HTML::Template::Pro; my $tmpl = HTML::Template::Pro - new(filename = 'test.tmpl'); print Content-Type: text/html\n\n; $tmpl - output(); ..and the HTML::Template::Pro template 'test.tmpl': !doctype html html body pblah blah/p /body /html I ran test.pl in the browser and everything was fine at first, no error.
