Oleg Kalnichevski resolved HTTPASYNC-17.
----------------------------------------
Resolution: Fixed
@Clinton
It turned out that adding caching support to streaming HTTP exchanges is a
major problem. Cache operations are inherently synchronous and it is almost
impossible to make the content stream backed by a caching entry behave
consistently with that coming directly from a socket channel. It either takes a
separate thread or the content consumer must be prepared to consume incoming
message content in one go completely defeating the whole idea of streaming HTTP
exchanges. For the time being I just made the streaming execute method
completely bypass the caching layer. In the future we could use NIO2 for file
based caches but this would require upgrade to Java 7.
Please review.
@Jon
There is now a lot of duplicated code in HttpClient and HttpAsyncClient caching
modules. It would be great to have some of it extracted to re-usable classes
and shared by both modules.
