[F8] Stop XML caching?

Hey guys, long time no thread; Anyway I’ll get to the point.

I need a way to stop XML files from caching. I have tried the xmlfile.load(file.xml?uniq=somerandomnumber) method, and it doesn’t seem to be curing the problem. I understand that this can be stopped with PHP, however, I cannot use PHP for this task.

XML caching is not a problem locally, only online, from the browsers, I cannot use any browser addons either as this file will be displayed to a vast audience and I can’t expect anyone to;
a) get an add on
b) clear their cache everytime they want to see the file.

Many thanks in advance, Nathan.
