It can't. The script has to be modified to remove the extra Gets that would be from cache.
My understanding is that to do that, you would have to inspect all the expirations in the server responses, or capture the same script in HTTP (like Fiddler) to see what Gets are not repeated.
There is one other topic here (http://www.qaforums.com/cgi-bin/foru...;f=36;t=000536)
I don't think it is correct because when I record the HTTP traffic (as w/Fiddler) there are no Get requests for say cached GIFs, etc. Somehow then OpenSTA is parsing the HTML itself and adding Gets for everything on the page.
Maybe dansut can respond...
