An L7 Rule is a single, simple logical test which returns either true or false.

Type: The L7 rule type. One of "Cookie", "File Type", "Header", "Host Name" or "Path".

• Cookie: The rule looks for a cookie named by the key parameter and compares it against the value parameter in the rule.
• Header: The rule looks for a header defined in the key parameter and compares it against the value parameter in the rule.
• File Type: The rule compares the last portion of the URI against the value parameter in the rule. (eg. "txt", "jpg", etc.)
• Path: The rule compares the path portion of the HTTP URI against the value parameter in the rule.
• Host Name: The rule does a comparison between the HTTP/1.1 hostname in the request against the value parameter in the rule.

Compare Type: The comparison type for the L7 rule. One of "Contains", "Ends With", "Equal To", "Regex" or "Starts With".

• Regex: Perl type regular expression matching.
• Starts With: String starts with.
• Ends With: String ends with.
• Contains: String contains.
• Equal To: String is equal to.

Key: The key to use for the comparison. For example, the name of the cookie to evaluate.

Value: The value to use for the comparison. For example, the file type to compare.

Invert: When true the logic of the rule is inverted. For example, with invert true, equal to would become not equal to.
