ALL Statements

An ALL statement is a line beginning with the keyword ALL, follo wed by z ero or m ore cond itions and

property settings. There are two conditions available in an ALL statement: acl= and protocol=. The

ALL statement acts as a match of first resort, before any filters are matched. An ALL statement has the

following general syntax:

ALL [acl=expression] [protocol=identifier] [property=value] ...
where

•acl=expression—An optional acl= condition expression. For more information, see

"Conditions" on page 301.

cache yes | no When set to no, do not cache the object. When set to yes, cache
certain objects that would not normally be cached. For more
information, see "force_cache()" on page 180.
case_insensitive yes | no When set to yes, match URLs without regard to case-sensitivity. By
default, all URLs are matched in a case-sensitive manner. This filter
should be set to match URLs served by operating systems such as
Windows, which is case-insensitive.
If case-insensitivity is to be used with a regular expression, you must
use (?i) to start the expression to be evaluated.
Note: In CPL, url= conditions have an optional .case_sensitive
modifier.
direct yes | no When set to yes, do not forward requests to a parent proxy or
SOCKS server. This property only applies when the device is
configured to forward requests.
label label_name Invokes a labeled definition. Acceptable characters are:
[a-zA-Z][a-zA-Z0-9]*
Note: In CPL, use the action( ) property. Label( ) is deprecated.
prefetch yes | no When set to yes, forces pipelining for an object. Set to no to prevent
the object from being pipelined. The default value is yes.
Note: In CPL, use the synonym pipeline( ) property.
Prefetch( ) is deprecated.
proxy_authentication yes | no When set to no, bypasses authentication for the URLs specified.
Note: In CPL, use the authenticate( ) property.
Proxy_authentication( ) is deprecated.
refresh yes | no When set to no, do not refresh the object if it is cached.
service yes | no When set to no, deny service to the URL.
Note: In CPL, use allow and deny. Service( ) is deprecated.
ttl seconds Sets the expiration time of a URL or object.
Notes:
•The advertisement property overrides the TTL.
• The HTTP command-line option "Force explicit
expirations: Never serve after" must be enabled. If
disabled, the CacheOS probabilistic refresh overrides the TTL
value.
