To prevent the client from using its cached copy, you'll need to have the server send an Expires header with the .html page. This can be accomplished by adding <meta http-equiv="Expires" content="0"> in the <head> section of the .html file. (RFC 2616 specifies that clients must treat an expires value of "0" as "already expired".) -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
