mod_python preprocess/filter before proxy

[=?iso-8859-1?Q?David_S=E1nchez_Mart=EDn?=]

Hi!

I've seen the message below in this python list, that seems to be
unanswered.

I'm trying to do the pretty same thing.

There's a way to preprocess the request with a mod_python handler and then
proxying it with mod_proxy?

Thank you very much in advance, and sorry for trying to revive such an old
message.

Cheers.

I use Apache2.0.44 and mod_python3.0.1.
I add ProxyPass and PythonHandler directives in httpd.conf
## httpd.conf
ProxyPass /test/ http://www.test.com
ProxyPassReverse /test/ http://www.test.com
<Location />
AddHandler python-program .htm .html
PythonHandler mptest
</Location>


And mptest.py:
from mod_python import apache
def handler(req):
req.write('Hello!!')
return apache.OK

ex. My apache server is www.server.com.
When I browsed the local server request(ex.
http://www.server.com/1.html),
I received 'Hello!!' response, the python handler worked well.
But when I browse the proxy request(ex.
http://www.server.com/test/1.html),
the response I received is the original content of
http://www.test.com/1.html, not 'Hello!!'.
The proxy requests didn't seem to be processed by mod_python handler.
How could I pre-process the proxy request before mod_proxy module?
Thanks a lot!!

Yes, use PythonInputFilter directive to specify an input filter.

http://www.modpython.org/live/current/doc-html/dir-filter-if.html

Input filters which modify the length of the data may be an issue
though when doing proxying however.

If you cant work it out, possibly more appropriate to take your
questions to the official mod_python mailing list referenced on the
mod_python site.
