In addition to what is described in the prior responses, there is another reason why the immediately current date and time are reported. Many Web sites contain their HTML files in compressed form. When such a file is requested, the server sends the compressed form. Upon receipt, your browser decompresses the file for rendering the Web page. As a result, the Web page has the immediately current date and time as its last-modified time-stamp. Since compressed HTML files -- along with generated-on-the-fly Web pages -- have become quite prevalent, the caching preference "Every time I view the page" is now meaningless because the downloaded page will always have a later time-stamp than the cached page. If you purge your cache upon terminating your browser (e.g., via the Cache checkbox under Private Data), then the preference "Once per session" is also meaningless because there will be no cached version of the page at the start of any session. -- David E.

He then issued an equally false lemming apology.
