An application that proxies WSGI requests to a remote server.
TODO:
* Send ``Via`` header? It's not clear to me this is a Via in the
style of a typical proxy.
* Other headers or metadata? I put in X-Forwarded-For, but that's it.
* Signed data of non-HTTP keys? This would be for things like
REMOTE_USER.
* Something to indicate what the original URL was? The original host,
scheme, and base path.
* Rewriting ``Location`` headers? mod_proxy does this.
* Rewriting body? (Probably not on this one -- that can be done with
a different middleware that wraps this middleware)
* Example::
use = egg:Paste#proxy
address = http://server3:8680/exist/rest/db/orgs/sch/config/
allowed_request_methods = GET

Make a WSGI application that proxies to another address:
``address``
the full URL ending with a trailing ``/``
``allowed_request_methods``:
a space seperated list of request methods (e.g., ``GET POST``)
``suppress_http_headers``
a space seperated list of http headers (lower case, without
the leading ``http_``) that should not be passed on to target
host

A proxy that sends the request just as it was given, including
respecting HTTP_HOST, wsgi.url_scheme, etc.
This is a way of translating WSGI requests directly to real HTTP
requests. All information goes in the environment; modify it to
modify the way the request is made.
If you specify ``force_host`` (and optionally ``force_scheme``)
then HTTP_HOST won't be used to determine where to connect to;
instead a specific host will be connected to, but the ``Host``
header in the request will remain intact.
