> Add different variants of non caching HTTP headers
> --------------------------------------------------
>
> Key: HADOOP-6607
> URL: https://issues.apache.org/jira/browse/HADOOP-6607
> Project: Hadoop Common
> Issue Type: Bug
> Components: io
> Affects Versions: 0.22.0
> Reporter: Steve Loughran
> Assignee: Alejandro Abdelnur
> Priority: Minor
> Fix For: 2.0.3-alpha
>
> Attachments: HADOOP-6607.patch, NoCachingFilter.java
>
>
> I'm suffering from proxy servers that are caching some of the HttpResponses
> that Hadoop generates in servlets/JSP pages. While the web ui is up to date,
> some of my build files are failing to pull stuff down because that is going
> via proxy -it sees an error page rather than the data
> # Every servlet should set a short expires header and disable caching,
> especially in proxies.
> # JSP pages should do it to
> # It's essential that error responses do it.
> Maybe this could be done in a filter. Otherwise something like
> {code}
> /**
> * Turn off caching and say that the response expires now
> * @param response the response
> */
> protected void disableCaching(HttpServletResponse response) {
> response.addDateHeader("Expires", System.currentTimeMillis());
> response.addHeader("Cache-Control", "no-cache");
> response.addHeader("Pragma", "no-cache");
> }
> {code}
> Before anyone rushes to do this, we should consult some HTTP experts in
> Yahoo! or Facebook to get the options right. It may be best to have, say, a
> 1s lifespan on everything.
