3.1. Content Rule Management
To define a new rule, click on "Create New". You must give the rule a name.
Hint: Rule names must be alphanumeric and start with a character.
Note, however, that rule names are unique and case sensitive, which means that giving a rule an existing
name will overwrite the rule of that name, and also that two different rules can exist in the form "Rule1" or
"rule1".
Next, decide the type of rule this will be: Prefix, Postfix or Regular Expression. These match to the URL as
follows:
/absolute/pathname/of/the/url/foo.html
|-> Prefix
Postfix ->|
|->
Regular Expression ->|
With the "Include host in URL" checkbox checked, the host name is also included in the URL match string:
www.a-host.com/absolute/pathname/of/the/url/foo.html
|-> Prefix
Postfix ->|
|->
Regular
Expression
->|
The protocol definition (e.g. http://) is ignored in all cases. Finally, enter the string that is to be matched.
Prefix and Postfix use standard strings and match exactly to what is entered. Regular Expression uses the
following syntax:
? - Match any single character
* - Match zero or more characters
$ - End of line
^ - Start of line
[ - Start of set, of which only one character will be matched. Must be terminated by ]
^ At start of a set matches a character not in the set.
\ - Escapes the next character
