This actually happens with IE 8 too (and can be observed with IE 9 in compatibility mode)
Details and workaround from chat transcript in #yui:
allenrabinovich: It has to do with the fact that IE caches the SWF file
allenrabinovich: And then loads it as if it were loading it from the filesystem
allenrabinovich: As opposed to from the network
allenrabinovich: And the SWF, thinking it was loaded from the filesystem, goes into the filesystem sandbox.
allenrabinovich: Right
allenrabinovich: So if you attach a random string to the SWF URL
allenrabinovich: As a GET var
allenrabinovich: Which would just get ignored
allenrabinovich: That would bust the cache.
allenrabinovich: So like "uploader.swf?" + "q=" + Math.random() type of thing
