-----------------------------------------
Hi, Oleg, another issue need to mention is when I use fiddle2 to inspect the
session, It shows that response head content length is 6400. If this result is
correct, does it mean the getContentLength() of HttpEntity is not reliable,
while we use this for output content from response?
thank you for your time.
Regards!
