Catalyst::TraitFor::Request::ProxyBase - Replace request base with value passed by HTTP proxy
package MyApp; use Moose; use namespace::autoclean; use Catalyst; use CatalystX::RoleApplicator; extends 'Catalyst'; __PACKAGE__->apply_request_class_roles(qw/ Catalyst::TraitFor::Request::ProxyBase /); __PACKAGE__->setup;
This module is a Moose::Role which allows you more flexibility in your application's deployment configurations when deployed behind a proxy.
The problem is that there is no standard way for a proxy to tell a backend server what the original URI for the request was, or if the request was initially SSL. (Yes, I do know about
X-Forwarded-Host, but they don't do enough)
This creates an issue for someone wanting to deploy the same cluster of application servers behind various URI endpoints.
Using this module, the request base (
$c->req->base) is replaced with the contents of the
X-Request-Base header, which is expected to be a full URI, for example:
This value will then be used as the base for uris constructed by
In addition the request uri (
$c->req->uri) will reflect the scheme and path specifed in the header.
On the frontend Proxy Apache, you would want to enable a Virtualhost config somewhat like this. The backend apache config stays unchanged.
<Virtualhost *:80> ProxyRequests Off <Location /preview> # You must have mod_headers enabled for that # RequestHeader set X-Request-Base /preview RequestHeader set X-Request-Base http://www.example.com/preview </Location> ProxyPass /preview http://my.vpn.host/ ProxyPassReverse /preview http://my.vpn.host/ </Virtualhost>
