Bug 1330947

- Proposed title of this feature request 

Feature request "wildcard router"

- What is the nature and description of the request?  
We would like to have an option in the Router to express that all (wildcard) subdomains of a DNS domain shall be regarded as the same route. Requests for that wilcard route shall be forwarded to the same service (the service associated with that route).

We believe that the use case for this is actually quite generic: One wants to deploy some in-bound proxy component, which would "pre-process" a requests, before it is forwarded to various services identified by the sub-domain name (or other wilcard parts ?) of the URL.

Specifically, we would like to do the following: A request comes in for myproject.jenkins.myopenshift.com. This is routed to a generic "Apache+SAML module" proxy, which handles SAML tokens. On successful verification of the token, it would forward the request to a back-end service located in a separate project. The back-end service could be identified by configuration, or by convention (which is the case in our case - we simply use mod_proxy+mod_rewrite to extract the target namespace from the original url). It is important that the proxy component is running in a separate project, because the operation & configuration of that, in out case is a platform responsibility, whereas the back-end service would be in a customer's responsibility.


- Is there already an existing RFE upstream or in Red Hat Bugzilla?  
No
