I'd like to set up a reverse proxy in IIS Express but it doesn't appear that Application Request Routing is supported (though I can't find anything which officially documents this).
My goal is to get a web server to proxy an incoming request to http://web.server/api/example to a second server (e.g. http://some.api.server/example) where web.server is running on IIS Express.
How might this be achieved?
No...you need ARR (application request routing) for doing this and arr can be installed only if you have IIS7/7.5 is installed.
