Squid Customized Authentication

["Ritesh Agrawal" <ritesh_security () rediffmail com>]

Hi All ,

  I want your support for configuring squid redirection .
 I have specific problem in squid authentication through  
redirection.

there are many default program for squid authentication like NCSA 
, PAM etc etc.

but i want to use customized authentication program through web 
page instead of traditional programs.

I have   developed  web page  for user authentication .
whenever any user open the Internet browser and type the URL in 
address box , this request would be transfered to my local web 
page through squid redirector facility with original URL as 
parameter.
My local web page authenticate user by asking user name and 
password . If authentication successful , then original URL will 
be restored and open the requested website in the browser 
otherwise shows 'Authentication Failed' message.
it is just concepts, i don't know how can it be implemented ,

e.g my redirect program redirect.pl

#!/usr/bin/perl
$|=1;
while (<>) {
   s@http://www.*.com@http://192.168.1.100/bpc/@;
   s@http://*.com@http://192.168.1.100/bpc/@;
  print;
}

squid.conf
redirect_program /usr/local/squid/etc/redirect.pl



so please suggest me about this project , If you know another 
method then inform me ASAP.
Thanks in advance
