cachedResponseForRequest won't be called after loading the same URL

Question

I subclassed NSURLCache, and overwrote cachedResponseForRequest, and changed the shared cache to my own cache object, to intercept every url request made by a UIWebView. It works perfectly at the first time, when the URL loaded into the UIWebView, it intercepts everything (css, jpg, etc). But when I try to load the same URL (eg. index.html), the cachedResponseForRequest method won't be called. If then I try with a different URL it works perfectly again.

I tried to modify the request's cachePolicy to every possible values, but nothing helped.

Finally I found a solution: after every URL request, you have to release all the UIWebViews, and re-create them before the next request. IMPORTANT: every release should occur before the new allocs.
