Proxy Rules Example—Using Regular Expression in Proxy Rules

The example file proxyrules_example7.xml file routes SPS requests based on nete:xprcond elements that contain regular expressions. Regular expressions are evaluated based on the URI and query string of a request.

In the file, the URI and query string of the request are evaluated against the three regular expressions defined in the nete:xpr elements. If a match is not found against the first nete:xpr element, the SPS tries to match it against the second, and finally the third regular expression. If no matches are found, the nete:xpr-default condition is used to handle the request.

The following table lists the results of requests using the regular expression proxy rules.
