      Description

      We should send a Cache-Control header on JSP pages so that HTTP/1.1 compliant caches can properly manage cached data.

      Currently our JSPs send:

      % curl -v http://nn1:50070/dfshealth.jsp
      ...
      < HTTP/1.1 200 OK
      < Content-Type: text/html; charset=utf-8
      < Expires: Thu, 01-Jan-1970 00:00:00 GMT
      < Set-Cookie: JSESSIONID=xtblchjm7o7j1y1f33r0mpmqp;Path=/
      < Content-Length: 3651
      < Server: Jetty(6.1.26)
      

      Based on a quick reading of RFC 2616 http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html I think we want to send Cache-Control: private, no-cache but I could be wrong. The Jetty docs http://docs.codehaus.org/display/JETTY/LastModifiedCacheControl indicate this is fairly straightforward.
