Subject [jira] Created: (SHINDIG-50) Change iframe URLs to include content hash
Date Fri, 01 Feb 2008 23:43:08 GMT
Change iframe URLs to include content hash
------------------------------------------

                 Key: SHINDIG-50
                 URL: https://issues.apache.org/jira/browse/SHINDIG-50
             Project: Shindig
          Issue Type: New Feature
          Components: Gadgets Server - Java
            Reporter: Graham Spencer
            Assignee: John Hjelmstad


The gadget server creates iframes that point to a "jail domain". The iframes include gadget
content as well as boilerplate Javascript.

To improve browser latency, the iframes should have long cache timeouts. However, this conflicts
with our goal of allowing developers to control the refresh rates of their gadget.xml files.
Therefore, the iframe URLs should include a hash of their contents, and the page itself should
have a long expiration time. This means that the browser will reload the iframe only when
the gadget.xml is changed.
