Problem Description:

We use CFHTTP for communication with some REST APIs using HTTPS. Sometimes there are networking issues that cause socket stuck in READ state. We have noticed that in ColdFusion 11 the timeout  is not triggered in this state, which causes CFHTTP to hang indefinitely and eventually this results in ColdFusion server hang. The threads hang in this state:

Below is a simple isolated example on how to reproduce this problem without simulating bad networking conditions. It includes 2 scripts:
1. A script that slowly returns data
2. A script with CFHTTP (over HTTPS) and Timeout lower than time for 1st script to return data.
It is expected for 2nd script to timeout before it is able to read all the data, however it is not the case.  

Steps to Reproduce:
script 1: testCFHttpTimeout.cfm (this script has to execute for longer than 1 second, increase index if necessary):
<cfloop index="randomindex" from="1" to="500000" step="1"> 

script 2: testAG.cfm (this script should load the 1st script via HTTPS):
<cfsetting requesttimeout="30" showdebugoutput="Yes" enablecfoutputonly="Yes">	

<cfhttp url="" method="GET" timeout="1"></cfhttp>	

<h1> Timeout Test : timeout seconds: 1</h1>


Actual Result:
>>>{ts '2015-04-13 09:33:23'}
>>> Timeout Test : timeout seconds: 1
>>>{ts '2015-04-13 09:33:32'}
Script ran for 9 seconds while timeout is 1 second

Expected Result:
>>>{ts '2015-04-13 09:33:23'}
>>> Timeout Test : timeout seconds: 1
>>>{ts '2015-04-13 09:33:24'}
Script should run for 1 second. CFHTTP should abort after 1 second of reading the data.

Any Workarounds:
None found.
