Here's an example of how to set it in HTML. Put the META tag inside the
HEAD tag.
<META HTTP-EQUIV="Expires" CONTENT="Tue, 04 Dec 1996 21:29:02 GMT">
Here's an example of how to set it in HTTP, along with 2 other headers.
This is from an embedded web server I built. The zero tells the browser to
expire the page immediately. Otherwise, replace 0 with another number to
indicate an amount of time, in minutes, after which the page should expire.
HTTP/1.1 200 OK
Content-Type: text/html
Expires: 0
In ASP, you can say
Response.Expires = 10
to expire in 10 minutes.
JSP probably has a similar syntax.
