[Paraview] paraview web issue

[Burlen Loring]

Hi Sebastien,

this is for a public deployment but I am testing in the browser while it 
locally logged into the system. This server is running ubuntu 11.04, 
apache 2.2.22. I hope that this isn't a roadblock.I can't easily upgrade.

your instructions for 14.04 went off OK but in 2 spots I had to find a 
work around:
1) proxy_wstunnel had to be installed manually, this went without a 
hitch and it loaded up without error
2) in the apache config I had to comment #Require all granted as that 
wasn't valid in 2.2

the session id was in the proxy.txt file and had the port number 9100 
which I see elsewhere in the logs, so that looks OK.

I'm attaching the launcher config.

the apache config is pasted below.
