How can I do with IIS 7 to make sending response header Last-Modified?
Into response header there are only Cache-Control:private.
I have also noted that with Apache that header is sent.
In my app , i have implemented HttpResponseCache to cache the responses so that it could be used instead of hitting the server. For a particular api , the server returns the header Cache-Control as no-cache, must-revalidate. It has the header ETag also. The problem is the response of this api is not cached.
