Lookup Cache not working when I cache the data using Response cache

Hi Team,

Please help on the below caching issue.

Step 1: API A ,I'm caching the back-end response using response cache policy.

Step2 : API B, I'm trying to access the cached response(Which is cached in the API A using Response cache policy) using lookup cache policy.

Here i'm not able to access the cached data but i have verified cache key's which is generated in the both policy and scope as well.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<LookupCache async="false" continueOnError="false" enabled="true" name="LC-B-API">
    <DisplayName>LC-B-API</DisplayName>
    <Properties/>
    <CacheKey>
        <Prefix>flow.apigee</Prefix>
        <KeyFragment ref="request.queryparam.aa"/>
    </CacheKey>
    <CacheResource>Test-Cache</CacheResource>
    <Scope>Exclusive</Scope>
    <AssignTo>LC_resp</AssignTo>
</LookupCache>
<ResponseCache async="false" continueOnError="false" enabled="true" name="RC-API-A">
    <DisplayName>RC-API-A</DisplayName>
    <Properties/>
    <CacheKey>
        <Prefix>flow.apigee</Prefix>
        <KeyFragment ref="request.queryparam.aa"/>
    </CacheKey>
    <CacheResource>Test-Cache</CacheResource>
    <Scope>Exclusive</Scope>
    <ExpirySettings>
        <TimeoutInSec>300</TimeoutInSec>
    </ExpirySettings>
    <SkipCachePopulation>response.status.code != 200</SkipCachePopulation>

Try using scope as Global in both the policies,

 <Scope>Global</Scope>

Exclusive scope will append proxy name to the cache name and hence you cannot access it from different proxies.

If we add a prefix in cache key, it will append the only prefix value as part of key.
