The only other approach that springs to mind is MIME multipart messages. I seem to remember that IE didn't support multipart/x-mixed-replace but some other multipart/mixed response might be workable.

The right solution for you will depend on many factors like the number of simultaneous users, presence of javascript, support for multipart/x-mixed-replace, is your file system stripped raid, etc. That said, I generally prefer dhoss's recommendation of a backend process because you can easily control things like disk thrashing and RAM usage.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
