Overview

Rack middleware for faking virtual hosts with url prefixes

Syntax is following:

/VirtualHostBase/<scheme>/<host>:<port><path>

When this middleware is enabled for example following request

GET http://localhost:8080/VirtualHostBase/http/fakedomain:1234/v3/users/bob

will be converted to following request

GET http://fakehost:1234/v3/users/bob

This is used to build correct uris inside the application when it is run under reverse proxies such as nginx. It's also usefull for testing.

Inspired by the "Virtual Host Monster" in Zope
