I have a number of subdomains, which are using crossdomain.xml file and I'm looking to a simple way of managing them all - which get semi-regularly updated. One way I've thought is a PHP script, which pushes and overwrites the xml file. The other, which I much prefer is a an apache redirect on a single file.
So, question is how would I, across multiple domains, redirect an xml on dom1.domain.com and dom2.wirewax.com to the same crossdomain.xml file without Flash getting upset about. i.e. not a 302 HTTP redirect, but internal file fetching.
