Freezed download via Wanproxy

[Ivan Pizhenko]

Hi Eliezer,

I am trying to achieve this test passing for Wanproxy. I am
insterested in doing this exactly with Wanproxy, not any other
software.
In this case, HTTP is used as sample, the thing should work regardless
to any application-level protocol.
It must work on the TCP/IP connection level.

WBR, Ivan.
