I'm sorry to trouble the list but I have not been able to get it
mod_python to work.  My setup is Python 2.2.2, Apache 2.0.47,
mod_python 3.0.3  Python root directory is e:\Python22  Apache's root
is E:\Program Files\Apache Group\Apache2  Windows 2k Professional

I have a sample python script sitting out in cgi-bin and it works just
fine.  The mptest file though, horks everytime.  Feel free to beat on
my server.

The error message is:
Premature end of script headers: mptest.py
Traceback (most recent call last):
  File "E:\Program Files\Apache Group\Apache2\cgi-bin\mptest.py", line 1, in ?
    from mod_python import apache
  File "E:\Python22\Lib\site-packages\mod_python\apache.py", line 67, in ?
    import _apache
ImportError: No module named _apache

Been here,
and I've been there

I believe I understand what that says and everything I could find about
it from the archived email messages but unless Apache is invoking the
python enviroment outside of apache, I have no clue what's going
wrong.  And if it is doing it outside, I have no idea how it got that

Saw both pythonhome and pythonpath referenced so I've touched both of


I'm at my wits end.  I know I can get Python running under IIS but as
I don't feel like patching daily, I thought I'd give Apache a whirl.
I've dutifully scoured the archives and applied what I saw there but
no go so anyone with some insight to offer would be worshiped from



The link for full archives does not work.
Fortunately, wget -R -a.gz worked just fine.
