That doesn't work, since the meta-tag is on the PAGE, not the element (which technically doesn't exist and is a figment of the server's imagination)
That is why it must first be parsed by the web server.
Therefore, any page which has a non-cacheable element (ie: an ad or time-sensitive data) must be marked non-cachable.
No sireee Karl - no the entire page but the specific element that is time sensitive.
Congratulations - you just specified that any shtml or asp page must be marked non-cachable, along with any time-sensitive or advertiser-sponsored page.
Yikes - Karl there are many differnt items on the page - they do not all have to have the same attributes - a cgi, an asp a banner-add, or maybe some other item on the page can be marked dynamic while the rest of the elements can be cached.
If that actually happens, then the proxy server operators will start shutting off recognition of the headers, and now we're right back where we started, along with the performance problems that this causes (forcing the traffic through a proxy server for EACH access actually HURTS performance, not helps it).
Yeah assuming that everyone who owns/operates a proxy/cache is a total and utter moron. -- I am nothing if not net-Q! - ras () poppa clubrich tiac net
