Conditional Match and Replace

An extension allowing you to create match and replace operations that execute only when a condition is matched (or not matched). The condition can be matched against the request Header/Body/All, or the response Header/Body/All. If the condition is matched, you can apply a match and replace rule against the specified area. You can create a condition that matches a request, then performs a match and replace in the response.

CMARs work in a chain, updating the request/response then moving to the next rule. If you have a CMAR that changes a request, and the subsequent rule matches a condition that was only present before the match and replace, it will not fire.

Conditions support regex and literal matching, as does the match and replace function.

Extension uses:

• Changing caching on some files
• Adding request headers (such as Authorization) to only some requests
• Alter a common string in the response for only some pages/targets.
• Change the target host or port a request is sent to
