Can't manage to make SDURLCache work about sdurlcache HOT 5 CLOSED

Your link leads to a 404. Anyway, about your issue, first thing to check is if the URL you are testing is cacheable or not (cache-control header etc.). For instance, http://google.com leads to a 302, which isn't cacheable.

What version of iOS are you running. Versions lower than 4, iOS do not call - (NSCachedURLResponse *)cachedResponseForRequest:(NSURLRequest *)request.

Ok, it's the headers then. I've changed the URL to another server and it works without problem. Which means I'll have to override the header info somehow because I don't control the remote server. What would be the best place to do this?

Also, the weird thing about the headers is that in these situations the files seem to be getting cached to disk, and iOS seems to be requesting them to later discard them. I tried overridding initWithCoder to force a cache policy of "always" but that didn't work.

I knew about the 3.x iOS since I have an old ipod touch, there the code wasn't being even called.

This is due to the way HTTP caching works : The client may store the response for doing conditional requests even if the response's cache directives don't allow to use the cached data without revalidation. The cache layer (this lib) doesn't control how the request layer (NSURLRequest) handles the cached data.

Because when an UIWebView is used you don't control the cache policy of subsequent NSURLRequests, you can't really force an UIWebView to use the cache even if HTTP server doesn't allow it. One solution though would be to trick NSURLRequest by rewriting the HTTP headers of a cached response before to send it back.

Thanks, I'll look into it.
