The possible cache policies are defined in ResourceRequestBase.h. They are: enum ResourceRequestCachePolicy { UseProtocolCachePolicy, // normal load ReloadIgnoringCacheData, // reload ReturnCacheDataElseLoad, // back/forward or encoding change - allow stale data ReturnCacheDataDontLoad // results of a post - allow stale data and only use cache }; These map directly to NSURLRequestCachePolicy from Cocoa land: http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSURLRequest_Class/Reference/Reference.html In practical terms, this means that when a user in Epiphany holds shift and clicks the reload button, not only will the request skip in the in-memory cache, it will also skip the disk cache. 480586 1 mrobinson 2011-10-08 11:45:19 -0700 This requires changes to the SoupCache in libsoup. My initial idea for this API would be something like this: soup_cache_set_message_cache_policy(msg, SOUP_CACHE_POLICY_IGNORE_CACHE); The policy could be stored as a piece of data attached to the message or the SoupCache could keep an internal table of policies. 480587 2 mrobinson 2011-10-08 11:49:45 -0700 The cache policy values also suggest that other disk cache implementations cache results of POST. Is this unusual? SoupCache only seems to cache GET requests. 480592 3 danw 2011-10-08 12:33:59 -0700 (In reply to comment #1) > This requires changes to the SoupCache in libsoup. My initial idea for this API would be something like this: soup_cache_set_message_cache_policy(msg, SOUP_CACHE_POLICY_IGNORE_CACHE); I'd say soup_message_set_cache_policy(msg, policy) (and get_cache_policy(), and a gobject property) 480595 4 mrobinson 2011-10-08 12:41:45 -0700 (In reply to comment #3) > (In reply to comment #1) > > This requires changes to the SoupCache in libsoup.
