I'm trying to get IIS to act as caching reverse proxy, but the cache hit is always 0%. And I really cannot tell why. And the docs always talk of a server farm setup, which is clearly not what I want.
I set up two sites, one with a binding to 127.0.0.1:80 (the web application) and one with a binding to *:443 (the reverse proxy). Now I have configured the RP site to forward requests with the URL Rewrite Module. That works.
Then I configured the Application Request Routing Cache on the IIS Server (why can this not be configured on a specific site???). The statistics sees the requests and counts them, but the cache hit rate remains 0%. What am I doing wrong?
