If I understood you correctly you want to copy a file from a webclient to the webserver. You can not install scripts on the webclient.

Here's one solution:

1) create a webpage with a form

The form contains a file-upload input tag, like so:

<FORM 
   ACTION="myupload.cgi" 
   METHOD="POST"
   ENCTYPE="multipart/form-data">
     Which file do you want to upload?
     <input type=file size=50 maxlength=100000 name="thefile">
[...other input tags...]
</FORM>
[download]

2) Now create a cgi-script

This script handles the uploaded data. with my example form the cgi-script need to be called "myupload.cgi". use the module CGI to get the data:

use CGI;

$query = new CGI;

$filename = $query->param('thefile');
while(<$filename>) {
        # do something with the data.
}
[download]

But don't just copy my code, read the man page of CGI!
