Use the Proxy Gateway widget to delete proxy groups from the built-in store.
A proxy gateway is a module that receives Web service requests and forwards them to an endpoint defined in a proxy group.
When you create a proxy gateway module, you define the proxy groups for the module. When you install your proxy gateway module, if the proxy groups do not exist in the built-in configuration store, they are automatically created.
When you uninstall your proxy gateway module, the proxy groups are not automatically deleted from the built-in configuration store. You must use the Proxy Gateway widget to delete the proxy groups and associated virtual services.
The proxy group is removed from the built-in configuration store, and the Proxy Gateway widget is refreshed.
