About URL Branching

The URL Branching action is useful for treating a few URLs differently from others. The action provides an Allow branch and a fallback branch. The URL Branching action provides these conditions for defining branch rules.

Equals
The URL must exactly match the specified URL.
Substring
The URL must contain the specified string.
Prefix Match
The URL must start with the specified string.
Suffix Match
The URL must end with the specified string.
Glob match
The URL must match the specified globbing pattern. These globbing patterns are supported:
  • * Matches any number of characters (none or one or more).
  • ? Matches a single character in these sets: [a-z] or [0-9] or [A-Za-z].
  • [characters] Matches one of the specified characters.
  • [^characters] Matches any characters except for those specified.
  • [!characters] Matches any characters except for those specified.

Note: To match many URLs, you might consider configuring URL categories in the Access > Secure Web Gateway area of the product and using Category Lookup in your per-request policy.
