5.6 HTTP cache
83
Note: Clients can always require a check for updates from the Web server (regardless of
the cache settings). Use a combination of the Ctrl+F5 keys to do this using either the
Microsoft Internet Explorer or the Firefox/Netscape/Mozilla/SeaMonkey browser. You can
set browsers so that they will check for updates automatically whenever a certain page
is opened (then you will only refresh the particular page).
URL Specific Settings
The default cache TTL of an object is not necessarily convenient for each page. You may
require not to cache an object or shorten its TTL (i.e. for pages that are accessed daily).
Use the URL specific settings button to open a dialog where TTL for a particular URL can
be defined.
Figure 5.24 HTTP cache — specific settings for URL
Rules within this dialog are ordered in a list where the rules are read one by one from
