> The req.proxyreq and req.uri attributes are not currently modifiable. If they were modifable,
it would be possible for a mod_python handler to trigger proxying of a request to some remote
site. For example:
> 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):]
>   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
