CFML runs on the CF server long before the mark-up gets sent to the client browser. Indeed in this case, no mark-up gets sent to the borser because as soon as CF encounters the <cflocation> it sends a redirect response to the client browser, which is done solely by sending a HTTP header, with no content at all.
