Perl CGI or CGI::Fast under Apache 2.2 on Debian Lenny

I have 2 different web servers on a Debian Lenny machine. One is running FastCGI (TRAC) and the other web server is running PHP and some CGI scripts. So I have currently the 2 Apache2 modules enabled (cgi and fcgi) and the 2 vhosts setup accordingly. I have no other particular interest for these both modules running at the same time.

So I want to keep ONLY Apache fastcgi module running as it looks to be the more efficient one.

Could you pls confirm the following assessments to be right or correct ?

1- I will have nothing to do/change for the TRAC site (already running fcgi)

2- I will have to tune the other web server vhost to be set with an handler to fastcgi scripts

3- I will have to change only the perl modules from "use CGI" to "use CGI::Fast"

4- I will be able to keep the rest of the perl existing CGI scripts w/o other changes

5- I do not need to use CGI::Ap开发者_运维问答ache but CGI::FastCGI (i/o the current CGI module) in the web server scripts

I hope my point is clear as it's all a bit foreign to me ...

Thx

EDIT:

thx for the hints to Naveed and J-16,

Here is what I did to get it working if it can help others :

• hum, installed CGI::Fast with CPAN, then it works better..

  On Debian with libperl already installed

  perl -MCPAN -e shell
  cpan> install CGI::Fast
  

• changed filename from *.cgi to *.fcgi,

• included the fastcgi while loop as adviced below by Naveed,
• setup the apache concerned vhost with the right handler for fastcgi (See fastcgi doc)
• enabled the Apache fastcgi module (a2enmod fastcgi) and disabled the cgi module,
• checked the fastcgi.conf file in the Apache settings,
• restarted Apache,
• checked the fastcgi running as an Apache sub process (ps -afx),
• fixed some script issues, already in.. but newly appearing when running fastcgi, as adviced (errors detected by checking the Apache logs),

• EDIT: adapted the file upload code as the initial script did not work anymore (still don't understand why), so I had to replace the while loop by a such one:

  open(FILE,">$upload_dir/$file_name")
  while ($bytes_count = read($file_query,$buffer,2096)) {
  $size += $bytes_count;
  print FILE $buffer;
  }
  close(FILE);
  

• done.

World is not yet perfect but it finally works.

You will have to do a little more than just change use CGI to use CGI::Fast. Make sure you wrap you CGI scripts with a while loop, as the documentation states http://p3rl.org/CGI::Fast

use CGI::Fast;
while (CGI::Fast->new()) {
    # The original CGI code goes in here
}
