Uploading PDB files to a CGI script

["Robert Fraczkiewicz" <robert - at - pauli.utmb.edu>]

 Dear Netters:
 We would like to start a web service where people would upload atomic
 coordinates in PDB format through an HTML form (e.g., by pasting them
 to TEXTAREA, or direct upload of a disk file via <INPUT
 TYPE="file">
 tag) and get results  back to their browsers. The form and CGI script work
 wonderfully as long as the PDB data size stays below ~20000 characters, which
 is insufficient for any practical application. Above this number the server
 times out without even touching the CGI script.
 Is there a limit on the amount of data a web client can transfer to
 a web server through forms? Personally, I don't believe that. I am
 sure many of you had faced similar problem. Any hints will be greatly
 appreciated and summarized on the list.
 With best regards,
