<br>

<br>I need to write a config that will set the "Cache-Control" value of a

<br>resource based on the age of the latter returned by the origin server.

<br>E.g if a resource is older than X hours then the Cache-Control should

<br>have a specific value.

<br>

<br>Anybody ever done that?

<br>

<br>I am hoping to be able to find something by starting with the

<br>"Last-Modified" value that is returned by the origin server.

<br>

<br>Regards,
