Apache 2.2 cut very long URLs from Wildfly

Question

I run a Wildfly 8 server with an Apache server.

We need a lot of options for searching. If you search something you can select many check boxes.

Normally every request will be execute. But if only one option isn't selected, we create a big URL.

We added 2 options in the Apache configuration.

LimitRequestLine 100000    
LimitRequestFieldsize 100000

Now we run in a limit. If the URL is longer than 8000 characters we get no error from Apache but the URL is truncated. The Apache log file saved only the truncated URL.

If I run the same process directly on Wildfly it works.

Do I need other configurations if I use Wildfly with Apache2 over proxypass?

ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/

Looks like LimitRequestLine has a bug when used with mod_proxy.

Similar issue was reported here Apache 2.4.16 Response Header value clipped.

Try using mod_jk instead, I have not tried this myself
