<p>Hello Fritz,</p>
<p>This seems to be the cause. "Cache-Control: must-revalidate" also
seems suspicious to me.<br>
</p>
<p>It looks like by default, Jetty does not inject the response
header. Here's an article on Stack Overflow about how to set it
up:</p>

<p>Hello Fritz,<o:p></o:p></p>
<p>Your media server controls the expiration policy of your
media files. The HTTP "Expires:" header is in charge of
telling the HTTP client when the file is to be re-requested.<o:p></o:p></p>
<p>I've failed check it myself because mrq12.it2media.de:8081
may not be accessible from the outside, but could it be that
the HTTP server returns a bogus "Expires:" header (e.g. if it
has a wrongly set system clock) or does not return it at all?<o:p></o:p></p>
<p>To verify, please simply call the following and see the
console output:<o:p></o:p></p>
<p>curl -D - <a
href="http://mrq12.it2media.de:8081/mr/v01/~~~200/mediafile/id/41511906/filetype/pdf?mimetype=true"
