Problems with Http11NioProtocol and proxy server

[bulau@xxxxxxxxx]

Hi,

we've build a web application with JSF
2.1 and RichFaces 4.5.13.Final running on JBoss EAP 6.4.12. We're also
using a Apache HTTP server 2.4.7 as a HTTPS/WSS proxy to access the application
for customers.

After we've changed the EAP http connector
to "org.apache.coyote.http11.Http11NioProtocol" (for using websockets/push),
ajax requests are often answered by HTTP 400 (Bad Request) or HTTP 500
(Bad Gateway).

We're switched back to the EAP http
connector "HTTP/1.1" and everything is working again as expected.

If we're accessing the EAP directly
(not via proxy) there is also no problem. It looks like that there is a
problem using Http11NioProtocol with Apache HTTP server as a proxy.

Is there anyone who run into the same
problem or has an idea how we can solove it?

Thanks & best regards
Marco
