Title: add http header for under firewall enviroment and proxy to cache

background:

I use Jenkins over the http proxy server.
The proxy server is caching contents, including Jenkins job configure.

Server: CentOS 5.x, Apache 2.2.x, Jenkins 1.454
Client: Windows XP SP3, Chrome 17

symptom:

I open the Job configuration page, sometime displayed configuration is too old.
And reload page, displayed current configuration.

expected:

Always display current configuration no reload.

fix:

add http header "cache-control".
I test this patch on the 1.455, I looked imploved.
