Does HttpClient in android do mem/disk cache when received content?

I do not know if the HttpClient in androi开发者_StackOverflowd have a built in cache system, then I can avoid to build my own.

There is support for caching (and a bunch of other features) in Gingerbread, but you have to switch to HttpUrlConnection. See http://android-developers.blogspot.com/2011/09/androids-http-clients.html
