Rather than using getstore, if you're always gonna be dropping it into the same file, use mirror (same syntax). This permits the webserver to reply with a "304 error" and no data transfer if you've already got the most up-to-date version of the file, and also sets the modtime of the file to the "last-modified" header so you have a clue as to the document's age.
