Just wrote a blog on this exact issue only using ExtJS (http://thecodeabode.blogspot.com/2010/10/cache-busting-ajax-requests-in-ie.html )

The problem was as I was using a specific url rewriting format I couldn't use conventional query string params (?param=value), so I had write the cache busting parameter as a posted variable instead..... I would have thought that using POST variables are a bit safer that GET, simply because a lot of MVC frameworks use the pattern

protocol://host/controller/action/param1/param2

and so the mapping of variable name to value is lost, and params are simply stacked... so when using a GET cache buster parameter

i.e. protocol://host/controller/action/param1/param2/no_cache122300201

no_cache122300201 can be mistaken for a $param3 parameter which could have a default value

i.e.

public function action($param1, $param2, $param3 = "default value") { //..// }

no chance of that happening with POSTED cache busters
