How can i configure Environment based Hostname for my proxy.

@Vinay Soni There are a few options here. The simplest would be to create targets servers with the same name in both test and prod, each referring to the corresponding target hostname that you want. You can refer to the apigee documentation for how to create and use target servers in your proxies: http://apigee.com/docs/management/apis/post/organi...

The other option is to do that in your proxies through either a javascript or conditional route rules because EDGE populates the environment.name flow variable for all runtime requests.

For the javascript option,

var env = context.getVariable("environment.name"))

would give you the environment that the proxy request hit and then based on that you can populate the corresponding target.url in the javascript.

For the conditional route rules, it would be something very similar:

<RouteRule name="test">
        <Condition>(environment.name = "test")</Condition>
        <HTTPTargetConnection>
            <URL>http://test.myapis.com</URL>
        </HTTPTargetConnection>
</RouteRule>
<RouteRule name="prod">
        <Condition>(environment.name = "prod")</Condition>
        <HTTPTargetConnection>
            <URL>http://prod.myapis.com</URL>
        </HTTPTargetConnection>
</RouteRule>
<RouteRule name="prod">
        <HTTPTargetConnection>
            <URL>http://default.myapis.com</URL>
        </HTTPTargetConnection>
</RouteRule>

Either of these approaches would work, but we recommend going by the target servers approach because then your proxy doesn't need all this logic or hardcoded URLs, and you can easily update the target server URLs using the management apis as and when you need.
