How often do we run into a use case where we don't want the requests routed to any particular target backends? Many times all we need is - a bunch of mediation,mock up responses and respond back to the client.
If we know the concept of route rules in Apigee, we can just tweak it a bit and have it work for our purpose.
Route rules have a configurable TargetEndpoint which can be conditionally executed. So based on a certain set of conditions I can route my requests to a particular backend.
Example of a regular route rule-
<RouteRule name="foo">
<Condition>(proxy.pathsuffix MatchesPath "/{version}/foo")</Condition> <TargetEndpoint>foo-target</TargetEndpoint>
</RouteRule> Now if I just have a route rule configured without having a TargetEndpoint, just based on the conditions, it will NOT route the request to any target backends.
<RouteRule name="no-target">
<Condition>(proxy.pathsuffix MatchesPath "/{version}/log"</Condition>
</RouteRule>We can just perform some request validations, do some mediation and mashup a response and send it back to the client - all within Apigee. This is a very common use case where if a backend is not yet ready, we could still mock up responses and have an api consumable for the clients.
