The ExpiresAbsolute property specifies the date and time at which a page cached on a browser expires. If the user returns to the same page before that date and time, the cached version is displayed. If a time is not specified, the page expires at midnight of that day. If a date is not specified, the page expires at the given time on the day that the script runs.
The following example specifies that the page will expire 15 seconds after 1:30 P.M. on May 31, 2001.
