PERL-CGI to pass a file to multiple server

Hi all,

We have three web servers (say a,b,c) that take a similar file (xyz.txt) and
gives the results.
Now, we want to make a meta-server with three check-boxes and only one input
form.
The purpose is to accept a single file and run the 'checked' server and
provide the results as two separate links
in next two pages.

Is it possible to pass files to different CGI/perl program using one single
form ? How ?
Any sample codes / applications around ?

Thanks in advance !
(: Happy PERL :)
