NSURLRequest Cache Policy Documentation Inaccurate
Although there is an extensive list of different cache policies listed in the documentation (https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSURLRequest_Class/Reference/Reference.html#//apple_ref/doc/c_ref/NSURLRequestUseProtocolCachePolicy), at least a few of these policies are not actually implemented, or actually do something different than suggested.
This is misleading and code result in unexpected results for applications.
Here's what's actually in NSURLRequest.h
NSURLRequestUseProtocolCachePolicy = 0,
NSURLRequestReloadIgnoringLocalCacheData = 1,
NSURLRequestReloadIgnoringLocalAndRemoteCacheData = 4, // Unimplemented
NSURLRequestReloadIgnoringCacheData = NSURLRequestReloadIgnoringLocalCacheData,
NSURLRequestReturnCacheDataElseLoad = 2,
NSURLRequestReturnCacheDataDontLoad = 3,
NSURLRequestReloadRevalidatingCacheData = 5, // Unimplemented
typedef NSUInteger NSURLRequestCachePolicy;
Steps to Reproduce:
Documentation would indicate which policies are not implemented and which behaviors are different than described.
Not the case.
