I think you may perhaps be going about this the wrong way. One can
cause a request to be proxied by doing something like the following.
This example uses mod_python, but could be done in C code or mod_perl
as well.
import posixpath
from mod_python import apache
def fixuphandler(req):
if req.proxyreq:
return apache.DECLINED
normalised_uri = posixpath.normpath(req.uri)
if normalised_uri:
if normalised_uri != '/' and req.uri[-1] == '/':
normalised_uri += '/'
length = len(req.filename)
length -= len(req.hlist.directory) - 1
length += len(req.path_info or '')
baseurl = normalised_uri[:-length]
path = normalised_uri[len(baseurl):]
# THIS IS THE IMPORTANT BIT WHICH SETS UP PROXY.
req.proxyreq = apache.PROXYREQ_REVERSE
req.uri = 'http://www.dscpl.com.au' + path
req.filename = 'proxy:%s' % req.uri
req.handler = 'proxy-server'
return apache.OK
If you didn't want to proxy a particular request, just return DECLINED
when you know so.
