Match Expression: URL | HTTP Header | XPath | Error Code

Matching expressions can test the message in several ways. For instance, in this lab you’ll be specifying
a matching expression that inspects the request URI for a specific pattern. Matching rules support the
following types of matching expressions:
● URL: A match template that inspects the URL for a specific pattern.
● HTTP: A match template that inspects the value of a specified HTTP header for a specific
pattern.
● HTTP Method: A match template that compares the specified HTTP method (POST, GET,
DELETE, etc.) against the value of the HTTP request line.
● Error Code: A match template that matches against specific error codes that may have
been raised by previously executed processing rules.
● XPath: A match template that uses the specified XPath expression to inspect the contents
of the XML message body.
When a message arrives into the processing policy, the policy will look at each processing rule, starting
with the first one, and evaluate its associated match expression. If the match expression evaluates to
True, the actions in that rule will be executed, otherwise the policy will look at the next rule. Once a
match rule evaluates to True, no other match rules will be evaluated. Only one processing rule will be
executed.
