A belated plug for Plack::Middleware::ReverseProxyPath (although it
sounds like your problem is solved).

http://search.cpan.org/~bowmanbs/Plack-Middleware-ReverseProxyPath-0.03/lib/Plack/Middleware/ReverseProxyPath.pm

I've not tried using this with Catalyst, but it's PSGI middleware so
should be fine.

I use the following header names:

X-Forwarded-Script-Name
The front-end prefix being forwarded FROM. This is the replacement.
The value of SCRIPT_NAME on the front-end.

X-Traversal-Path
The back-end prefix being forwarded TO. This is to be replaced.
This is the part of the back-end URI that is just plumbing which
should be hidden from the app.

X-Forwarded-Script-Name follows the X-Forwarded-* pattern established
by other headers (the SCRIPT_NAME on the front end) and matches PSGI names.
X-Traversal-Path was inspired by a similar Python/wsgi middleware.

However, I'd like to use the defacto standard names, if they exist.
Is X-Forwarded-Path in common use?

I might also add support for X-Request-Base and a combined middleware
similar to Catalyst::TraitFor::Request::ProxyBase, thanks for the
inspiration.

Brad

Thanks t0m,

I installed your module and it works great - thanks for writing etc.

I guess what I may have been pertaining to is that X-Forwarded-Path
using_frontend_proxy doesn't seem to be implemented although on the
'official'? wiki
(http://wiki.catalystframework.org/wiki/wikicookbook/frontendproxy) it
is documented.

Best wishes
Stephen

 You probably want to be using Catalyst::TraitFor::Request::ProxyBase, which I 
 wrote specifically for this use-case however :)

AW: [Catalyst] X-Forwarded-Path

2012-10-10 Thread Trzeciak, Rainer

Hi Stephan,
what about
ProxyPass http://backend.mydomain.ac.uk:5000/CUFSE (please note the /CUFSE at 
the end) ?
You can then skip: RequestHeader set X-Forwarded-Path '/CUFSE'

Kind regards,
Rainer
