RE: Time to live for classpath references
Hi Peter,
There is a RFE to support caching control directly in the Restlet API:
"Support caching HTTP headers"
http://restlet.tigris.org/issues/show_bug.cgi?id=213
Otherwise, there is a "timeToLive" parameter on local connectors such as
CLAP, FILE:
http://www.restlet.org/documentation/snapshot/engine/org/restlet/engine/loca
l/LocalClientHelper.html
By default the value is 600 second but due to a bug, it wasn't applied to
the CLAP representations' expiration date. I've fixed this in SVN trunk and
1.1 branch. Let me know if it works for you!
Best regards,
Jerome Louvel

Thanks,
I'll try that -- at least you saved me from finding the hack myself :-)
Is there an RFE to vote upon? I think controlling the caches can be quite
important, especially if you have lots of small objects. I'd personally even
go as far as having a parameter on the constructor of directory that toggles
infinite caching. If the resource is truly static with a URI encoding its
revision, then you will never need the cache expiry.

Re: Time to live for classpath references
We still do this:
http://gogoego.googlecode.com/svn/trunk/modules/com.solertium.util.restlet/src/com/solertium/util/restlet/ClapCacheDirectory.java
If there's a better way, I'd love to adopt it too.
