What is important here is how you are requesting the page. Having the
page open in Firefox, and hitting reload will cause a "Cache-Control:
max-age=0" header to be sent which requires revalidation of the page in
question (see
http://www.w3.org/Protocols/HTTP/Issues/reload-operations.html).

Use one of the cacheability engines if possible, or set your browser
cache to 0 (both mem and disk) and surf to the page using a bookmark.
