The following code uses Stingray's RESTful API to delete a pool. The code is written in TrafficScript. This rule deletes the "tstest" pool created by the stmrest_addpool example. To delete a resource you do a HTTP DELETE on the URI for the resource. If the delete is successful a 204 HTTP status code will be returned. Subroutines in stmrestclient are used to do the actual RESTful API calls. stmrestclient is attached to the article Tech Tip: Using the RESTful Control API with TrafficScript - Overview.

# stmrest_deletepool
#
# This rule deletes the pool "tspool".
#
# To run this rule add it as a request rule to an HTTP Virtual Server and in a
# browser enter the path /rest/deletepool.
#
# It uses the subroutines in stmrestclient

Running the example
This rule should be added as a request rule to a Virtual Server and run with the URL:
http://<hostname>/rest/deletepool
Pool tstest deleted
