I attempted to upload 3 pdf files of various
lengths and got the following error message:

  "A network error occurred while Netscape
   was sending data.
   (Network Error: Broken pipe)

   Try connecting again."

Environment:  Solaris 2.6, Netscape 4.5

One of the files was over 1000K.

I retried with a single files of 40K and 80K
approximate length with success.  Then a
couple of files over 500K combined with
success.

Then 2 files of combined 1000K with success:

  thanks for the upload
  content-length = 1005486
  bytes read     = 1005486
  (that's the total size of the HTTP request, *not* the
  size of the file(s) you uploaded.  It should be a bit larger
  than the total size of the uploaded file(s).)

Then again a single 1000K file (a different one) which
breaks with the same error message as above.  The
limitation for my system appears to be a single file
length of 1000K.
