Intel 1520 manual Configuring caching rules

Option (Continued)	Description (Continued)
Set FTP objects expiry	FTP objects carry no time stamp or date
	information. The appliance considers them
	fresh for the amount of time specified here.
	This "freshness" time is counted from the
	time the object arrives in the cache.
	Enter the time in seconds and press Enter.
	After pressing Enter, press CTRL-X to save
	your changes and return to the previous
	screen.
Internet Explorer options	Versions of Microsoft Internet Explorer do not
	request cache reloads from reverse proxies
	and transparent caches when the user
	presses the browser Refresh button. This
	behavior can prevent users from manually
	reloading content directly from the origin
	servers. You can configure the appliance to
	treat Microsoft Internet Explorer requests
	more conservatively. Doing so provides
	fresher content at the cost of serving fewer
	documents from cache.
	Internet Explorer requests force a check with
	the origin server.
	Select from one of the following options and
	press Enter. After pressing Enter press
	CTRL-X to save your changes and return to
	the previous screen.

✔How long to keep (pin) particular objects in the cache

✔How long to consider cached objects as fresh

✔Whether to ignore no-cache directories from the server
