Win2000 Professional SP1
Apache 1.3.20 pre-built release from apache.org
Netscape Navigator 4.72
IE 5.5
Related to bug #7623 - no feasible resolution was found there...

When submitting html forms with a "post" method to server via 
Netscape Navigator (4.72) on localhost machine, the server takes
a VERY long time to process the form (in excess of 15 seconds),
no matter how simple or complicated the form or processing may
be on the server end.

A few observations... 

1) This problem does not occur when accessed
via IE 5.5 on localhost - the form is processed in normal time. 
2) The problem does not occur if the form is submitted using a
"get" method, in both Netscape and IE.
3) Problem does not occur when accessed from other machines on
local network (non-localhost access).
4) I don't believe the problem occured under WinNT with same
browser and Apache versions... seems to be combo of Win2000,
Netscape 4.7x and Apache 1.3.20(also 19).
5) We have seen the same problem occur on 3 separate machines, each
running Win2000, with default Apache 1.3.20 installations (only
addition is Jakarta 3.2.x - removing Jakarta does not clear up the
issue either)
6) Server-side CGI processing language (who's handling the request)
does not appear to matter... same behavior noticed in JSP, PHP, and

I would use a GET method in the form, however the data I need to
process is larger than the maximum "get" URL length, so I must use
a form POST method.
Install Apache 1.3.20 on a Win2000 computer.
Install Netscape Navigator 4.72.
Create a simple form with a "post" method.
Process the form (and generate response) through Perl.
Access the same form through IE and note the extreme speed difference.
