[users@httpd] Bizzare apache 1.3 behavior (2 HTTP Responses for 1 Request?!)
I have a small webapp I am running under Apache 1.3 using the mod_python
handler, and I am getting a bizzare reaction from Apache on it on one (but
only one!) of the servers I am trying to run it on.
When I do a request (get or post) apache returns TWO http
responses!! one is the correct response from the python script,
the second looks like an apache-generated html page that says
the url is not found. The http response code of both is 200 Ok.
Now the apache config on the two servers is not identical (I wish it was, but
it isn't and there isn't much I can do about it.) I'm guessing that the
mod_python handler is running, producing output, and then for some reason
Apache is running a second handler...?
Does anyone know if some misconfig in httpd.conf could cause that?
If so, what should I look for? I haven't a clue how to debug this at the
moment . I tried asking on the mod_python list to see if it could be a bug in
that, but they haven't a clue either.
here's a snippet of the conf file that is responsible for setting up this
webapp :
++++++++++++++++++++++++++++++++++
<Location /xmlrpc>
<IfModule mod_python.c>
PythonPath "sys.path + ['/home/core/python/lib']"
SetHandler python-program
PythonInterpreter XMLRPCInterpreter
PythonHandler XMLRPCHandler
PythonOption CORE_ROOT /home/core
</IfModule>
</Location>
++++++++++++++++++++++++++++++++++
The oddest thing is that this code works fine on another server!
Note the Server: line for the versions...
Here is a an example request and response(s): (note this is running under
SSL. )

The other server (which works fine) is thus:
Server: Apache/1.3.29 (Debian GNU/Linux) mod_python/2.7.10 Python/2.2.3+
mod_gzip/1.3.26.1a PHP/4.3.4 mod_fastcgi/2.4.0 mod_ssl/2.8.16 OpenSSL/0.9.7c
DAV/1.0.3
Could a botched config in the httpd.conf do this somehow? If so what
should I be looking for? I can't just compare the http.conf's on the two
machines, alas, as they are too different, and I don't know where to begin.
Note that regular html pages, and another mod_python app running on the same
servers (different handler & interpreter) do NOT exhibit this issue.
(yes, I would prefer to have my servers have the same config, but these are
production company servers, thus I have to take what we've got. :P )
