Nested conditions in conditional flow.

How does apigee work with nested conditions as in the below. Is it the right syntax below?

<Flows>    <Flow name="OptionsPreFlight">        <Request/>        <Response>            <Step>                <Name>add-cors</Name>            </Step>            <Condition>request.verb == "GET"</Condition>        </Response>        <Condition>request.verb == "OPTIONS"</Condition>    </Flow></Flows>

I wanted the condition request.verb == “GET” to be executed for response only and not for request.

How does apigee interpret the above 2 conditions for the Response?

My intention is to add-cors before I send the response to the client. I cannot remove the existing condition for “OPTIONS”.

Do we see any error if apigee tries to add a header to the response which is already present in the response headers?

@Yashwanth Koundinya Saraswathibhatla,

Below is the interpretation of the conditions in Apigee for your code.

The options preflight flow is executed when a preflight request with options verb is sent.

The add-cors policy is never executed because the satisfying condition for the outer flow is request verb = options, so the condition defined for the step, request verb=get will never be satisfied.
