Thanks!

I've managed to get this working now, but I'm hitting problems
with pages in iframes. Basically, I have some svg files that are changed
often. They can be <embed>ed or <iframe>d in an html page. When I access
the svg files directly, they don't cache, but when I access the parent
page, unless the url changes it doesn't reload the svg file. I've managed
to work around it because the parent file is actually dynamically
generated, so I can add a ?param=somerandomvalue to the end of the iframe
src url, but it seems a bit clunky. Am open to suggestions for a nicer way
of doing this?
