> Key: HADOOP-8998
> URL: https://issues.apache.org/jira/browse/HADOOP-8998
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 2.0.2-alpha
> Reporter: Andy Isaacson
> Assignee: Alejandro Abdelnur
> Priority: Minor
> Attachments: HADOOP-8998.patch

>
> 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:
> {noformat}
> % 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)
> {noformat}
> 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.
