i am currently developing the back and frontend for a project which tries to be a meta-ressource for independent media works (http://mmm.ok.ag)

MMM is a publishing platform for visual media productions (moving media) of emerging contemporary artists in various genres.

if people want to upload their video-works i want to create a file-uploading-part which has to handle rather big files (up to ~650MB in the "worst" case)
we have an anonymous ftp-upload, but i wanted to build a web-driven upload from the submission form of the works:

my aim:
  1. upload form with CGI::FormBuilder (the CGI doesn't mean that it's only usable with CGI.pm, also usable with mod_perl)
  2. submit the form to a new window (respectively perl/cgi script)
  3. this window should show the uploading progress
for the last part of this i wanted to use a frame which is 100% width and height, the invisible frame processes the uploading request, the visible frame (with http-equiv-refresh) shows the uploading progress.

there are several RFCs about Form Handling, i read most of them, but my problem now with perl is the following:

i want to extract the Content-length of the http header, and compare it to the temporary file on the server or the data transfered so far.

how to solve this issues in perl/cgi/mod_perl?
thanks a lot,
parasew
