Richard Mortimer commented on JENKINS-13217:
--------------------------------------------
I think that the observed behaviour is down to the loosely defined semantics of
HTTP 302 responses. In this case we want HTTP/1.1 307 behaviour instead of
HTTP/1.1 303 type behaviour.
That said in this instance I think that the correct fix is to just put the
image URL inline in the img src attribute. The tooltip and alt attributes are
already fixed inline so putting the actual icon URL inline seems appropriate
too.

> Key: JENKINS-13217
> URL: https://issues.jenkins-ci.org/browse/JENKINS-13217
> Project: Jenkins
> Issue Type: Bug
> Components: core
> Affects Versions: current
> Environment: Jenkins 1.456/ Ubuntu 11.10
> Reporter: Richard Mortimer
> Assignee: Richard Mortimer
> Priority: Minor
>
> The main build status page shows a 48x48 icon representing the build status.
> If you visit the page during the build this shows a flashing "build in
> progress" icon. However when the build stops the "build in progress" icon
> continues to be displayed.
> This is due to browser caching behaviour. For example the recent build at the
> following URL
> http://ci.jenkins-ci.org/job/tools_maven-hpi-plugin-maven-2.x/40/
> During the build the relevant markup was
> {code}
> <img height="48" alt="In progress" width="48" src="buildStatus" tooltip="In
> progress" />
> Build #40
> (23-Mar-2012 01:18:30)
> {code}
> The request for buildStatus returned a HTTP 302 redirect to
> {code}
> Location:http://ci.jenkins-ci.org/images/48x48/blue_anime.gif
> {code}
> The combination of a 302 redirect and caching headers in the gif cause the
> browser to not re-request buildStatus within the same browser session.
> http://ci.jenkins-ci.org/job/tools_maven-hpi-plugin-maven-2.x/40/buildStatus
> Note this is unrelated to the recent changes for caching of images etc. I
> have noticed this in the past but have not had time to investigate before now.
