Response cache break timeout based on route resource

[#1]

Can response cache timeouts vary across API resources?

For example, this works as expected.

API response cache for 1hr.

http://test.net/v1/base/alpha

<CacheKey>

<Prefix/>

<KeyFragment ref="request.uri" type="string"/>

</CacheKey>

<Scope>Exclusive</Scope>

<ExpirySettings>

<ExpiryDate/>

</TimeOfDay>

<TimeoutInSec ref="">3600</TimeoutInSec>

</ExpirySettings>

How can i configure Apigee to only cache this response for 15 secs?

http://test.net/v1/base/beta

Is there a way to add conditional logic into "TimeoutInSec" ?

<TimeoutInSec ref="">3600</TimeoutInSec>

Thanks in advance
