Problem Description: Our CF server must go through a proxy to get access to machines outside its local subnet.  However, we need it to be able to access its siblings in the subnet directly without going through the proxy.  We've added the standard JVM startup arguments for specifying a proxy to http/https requests (http.proxyHost, http.proxyPort, http.nonProxyHosts) and the cfhttp call is respecting the host and port, but ignorning the nonProxyHosts.  So even if the host matches the http.nonProxyHosts, the request goes through the proxy.  

Steps to Reproduce:  Add the following JVM arguments to CF startup with values filled in:
-Dhttp.nonProxyHosts="<your server name>"

Restart the CF service.  Then create a page with this content (I'm running on Windows):

<cfparam name="mode" default="make_request">
<cfif mode eq "make_request">
	<cfhttp url="https://#cgi.server_name##cgi.script_name#?mode=debugging" throwOnError="no">
<cfset client_ip = cgi.remote_host>
<cfset client_dns="">
<cfexecute name="nslookup" arguments="#client_ip#" variable="client_dns" timeout="5">
ip: #client_ip#...#client_dns#
server: #cgi.server_name#

Actual Result:  The actual result is that the cgi.remote_host variable will contain the IP address of the proxy

Expected Result:  The cgi.remote_host should contain the IP address of the current machine

Any Workarounds:  None

This problem also exists in CF10 (10,0,16,293499) and versions of java 1.7.0_79 and 1.8.0_51 - but I works with Java 1.7.0_75 on windows 7

I just tired this used Java 1.7.0_75 on Windows 2008 server (using CF11) and it still doesn't work. The request still goes through the proxy. I would check your config/code again

Same issue here, quite severe bug as we need the proxy so CF can check for updates but now even localhost http requests are routed through the proxy (CF11 on centos)

We would appreciate a hotfix for this, and/or please let us know which CF11 update will contain the actual fix. It is unfortunately NOT listed in the Update 7 release notes.

This happened to me as well. CF is trying to make things more "simplistic", but actually causes some issues. In this case, it is adding those quotes to your: -Dhttp.nonProxyHosts="<your server name>" So, the options come out as: -Dhttp.nonProxyHosts=""<your server name>"" The fix is to set that property without any quotes: -Dhttp.nonProxyHosts=<your server name>
