Does NSURLCache
transparently handle ETags received by server?
I mean: does it automatically store ETags for each URL request and then send the appropriate If-None-Match
when a request to the same URL is submitted?
Or do I have to manage it by myself?
yes it does handle it transparently if you set its cache mode:
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]
cachePolicy: NSURLRequestUseProtocolCachePolicy
timeoutInterval:60];
note: you cannot see the header in the request at all and if a 304 response is returned by the server you will only see the 200 response that it transparently loaded from the cache.
