Bug 1180745

Created attachment 978387 [details]
patch against centos git repo to fix wss support, using wss as a target to mod_rewrite and enabling the websockets proxy module

Description of problem:
for our application, using mod_proxy_wstunnel on el 7 revealed 3 problems:

1) not included in conf.modules.d/00-proxy.conf
2) mod_rewrite does not support proxy to ws:// URIs as a target
3) mod_proxy_wstunnel does not support SSL (wss://)

Version-Release number of selected component (if applicable):
httpd-2.4.6-18

How reproducible:
always

Steps to Reproduce:
1. install httpd
2. try using a config like the following in apache to proxy to a websockets application:

RewriteEngine on
RewriteRule ^/ws-app(.*) wss://localhost:3301/ws-app$1 [P]

assuming you have a websockets application on localhost:3301, you should be able to successfully proxy to it.

Actual results:
http request fails

Expected results:
connection proxied through http to actual websockets application

Additional info:
I have included a patch against the centos httpd sources - which AFAICT is the canonical place for this. Feel free to have it and mangle as needed.
