const mixinafBedSheet::IeAjaxCacheBustingFilter

Prevents IE from caching Ajax and CORS requests. Sets the following response http headers:

Cache-Control: max-age=0,no-cache,no-store,post-check=0,pre-check=0"
Expires:       Mon, 26 Jul 1997 05:00:00 GMT"

This is by far, much preferable, to the client setting a cache busting query string to the request url (yuck!).

To enable, just contribute the filter to the HttpPipeline:

@Contribute { serviceType=HttpPipeline# }
  static Void contributeHttpPipeline(OrderedConfig conf) {
  ...
  conf.addOrdered("IeAjaxCacheBustingFilter", conf.autobuild(IeAjaxCacheBustingFilter#), ["after: BedSheetFilters"])
  ...
}
