No content length header causes patience page loop.

ProxySG Software - SGOS
Issue/Introduction
We rarely use patience page feature by configuring ICAP Feedback with our Content Analysis(CAS). If Content length header is not exist in the response from the OCS, ProxySG will show us a patience page but it continues forever, never end.
Cause
This is a limitation of the SGOS.
Environment
Release : All ProxySG OS
Component : ICAP
Resolution
The easy way to solve the issue is to use Trickle object data from stat/end instead of patience page.
Additional Information
As a well know behavior of the response header from the OCS, "Content length" header is not simultaneously used with "Transfer-encoding: chunked". So if OCS returns a "Transfer-encoding: chunked" header, Proxy SG will be in the patience page loop. In order to avoid this issue with the policy, here is an example.
