This set of files shows a bug that occurs when doing POST requests
via the CGIHTTPServer.py module in Python 2.1 The testpost.html
file when accessed via Internet Explorer 5.5 from webserver.py
should show this bug. On short POST requests IE will end up
doing a second POST and then displaying an error message while
longer POSTs will be followed by a second POST and then a GET.

The problem appears to be specific to the interaction of IE and
the handling of windows sockets in Python in the CGIHTTPServer.py
module which relies on BaseHTTPServer.py, SocketServer.py...

posttestwebserver.py is currently setup to use C:\tmp\testpost as the
document root, so either move the "testpost" folder to C:\tmp or change
the directory to wherever the testpost folder is located. Start the
server using the .bat file and bring up .html page with something like:
  http://localhost/testpost.html

The bug should occur when you try:
  Test short CGI response with POST
or
  Test long CGI response with POST

The other requests should work fine. The bug will occur regardless of
whether IE is set to use HTTP/1.0 or HTTP/1.1. The bug doesn't appear
to occur when going through a simple proxy. You can also get the bug
to occur using a remote IE client (either on a LAN or over the Net).
In addition, it doesn't appear to matter whether running with unbuffered
binary pipes (python -u) or not. I also tested against my modified
CGIHTTPServer.py See the bug I posted at:
http://sourceforge.net/tracker/?func=detail&atid=105470&aid=427345&group_id=5470

My configuration:
Windows 2000 Pro, SP2
AMD 1.2GHz
256MB RAM
ActiveStatet Python 2.1 (build 210)
Internet Explorer 5.5 (5.50.4522.1800)

Mark Lutz (lutz@rmi.net) has confirmed this bug as well on Windows 98.
