Cacheing on XSLT service

To speed things up on the experimental RSS-in-Mozilla-sidebar thingy, I’ve added in some cacheing (using a little MySQL db) to the simple XSL-Transform service that’s used to transform RSS to HTML on the fly, for inclusion into the sidebar. It makes it a lot faster, obviously, and takes a bit of strain off our poor old Celeron. I’ve exposed the gubbins a bit, in that it’s possible to specify a ‘cachelife’ parameter on the call. So if you want to customise the URL passed in the sidebar.addPanel() call, you can send this now: ? xmlfile=http://url/of/rss.feed & xslfile= & cachelife=30

The ‘cachelife’ parameter says “give me the cached version as long as it’s no more than N (30, here) minutes old … otherwise pull the RSS and transform it for me afresh, baby”. (It’s all explained briefly on a little homepage, which you get if you don’t specify an xslfile or xmlfile parameter.)

The existing sidebar button will continue to work fine, in that a default of 60 (minutes) is assumed if no ‘cachelife’ parameter is specified.
