[All Salesforce MuleSoft Developer II Questions]

A developer deploys an API to CloudHub and applies an OAuth policy on API Manager. During testing, the API response is slow, so the developer reconfigures the API so that the out-of-the-box HTTP Caching policy is applied first, and the OAuth API policy is applied second.

What will happen when an HTTP request is received?

AIn case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; then the cached response is returned to the caller

BIn case of a cache it, only the HTTP Caching policy is evaluating; then the cached response is returned to the caller

CIn case of a cache miss, only the HTTP Caching policy is evaluated; then the API retrieves the data from the API implementation, and the policy stores the data to be cached in Object Store

DIn case of a cache miss, both the OAuth and HTTP Caching policies are evaluated; then the API retrieves the data from the API implementation, and the policy does not store the data in Object Store

Show Suggested Answer

Suggested Answer: B

When an HTTP request is received and the HTTP Caching policy is applied first, it checks if there is a cached response for that request in Object Store. If there is a cache hit, meaning that a valid cached response exists, then only the HTTP Caching policy is evaluated and the cached response is returned to the caller without invoking the OAuth policy or the API implementation. If there is a cache miss, meaning that no valid cached response exists, then both the HTTP Caching policy and the OAuth policy are evaluated before invoking the API implementation.

I'm going with option C. If there's a cache miss, the HTTP Caching policy should evaluate first, then the API should retrieve the data and store it in the Object Store.

Ha! I bet the developer is regretting that decision to apply the OAuth policy after the HTTP Caching policy. Talk about a recipe for disaster!

Option D seems more logical to me. If there's a cache miss, both the OAuth and HTTP Caching policies should be evaluated before the API retrieves the data from the implementation.

You're right, I didn't consider that. So the correct answer might actually be D, where both OAuth and HTTP Caching policies are evaluated in case of a cache miss.

I think option B is the correct answer. In the case of a cache hit, only the HTTP Caching policy should be evaluated, and the cached response should be returned to the caller.

That makes sense, but wouldn't the OAuth policy also be evaluated in case of a cache miss?

I disagree, I believe the answer is C. The HTTP Caching policy is evaluated in case of a cache miss, and the data is retrieved from the API implementation.

I think the answer is B, because only the HTTP Caching policy is evaluated in case of a cache hit.
