ReverseProxy for IIS 6.0 in CS using ASP.NET

Problem to solve

We want to embed content from a internal webserver e.g. http://foo to our public webserver http://sar.informatik.hu-berbin.de. In particular the frontend request http://sar.informatik.hu-berbin.de/test/bla.html should get the response for http://foo/dir/bla.html. Thus the mapping is:

• http://sar.informatik.hu-berbin.de/test -> http://foo/dir.

From outside this sould be look like a local web directory.
