| After (seconds) |
Select this option to have the cache/proxy server check the origin server for updated content after a specified number of seconds has passed. The default setting is 86,400 seconds (24 hours). If the content on the origin server is newer than the content on the cache/proxy server, the cache/proxy server will update its content. |
| Immediately |
Select this option to have the cache/proxy server update the content from the origin server each time a client requests the content from the cache/proxy server. |
| Never |
Select this option to have the cache/proxy server never update the content from the origin server. In order to update the content, the cache/proxy server administrator must explicitly request a new version of the content. |
