Dynamic Page #1 (with expiration)

This is a dynamic ASP page. When the server returns this page, the Expires header will be set five minutes (300 seconds) in the future. If you switch back to this page within the five minutes of the first load, the browser will not re-fetch the page from the server but use a cached copy instead. Note that the Last-modified header is still absent.

The page was generated at Monday, December 09, 2019 2:50:41 AM (local time on the server) and is set to expire in 5 minutes.

To test the caching behavior, switch to the second dynamic page.


Sample request/response on first load ...

    

Subsequent loads (when requested by the browser after the page expires) are no different from the first load.
