API Management

Question:

What rule should be used to serve this URL from cache: https://myapi.azure-api.net/items/123456?

<cache-lookup><vary-by-query-parameter /></cache-lookup>
<cache-lookup-value value="itemId" />
<cache-lookup-value key="itemId" />
<cache-lookup-value value="items" />
<cache-lookup><vary-by-query-parameter>itemId</vary-by-query-parameter></cache-lookup>
<cache-lookup><vary-by-query-parameter>items</vary-by-query-parameter></cache-lookup>
<cache-lookup-value key="items" />

Answer:

This URL has no query parameters, so you use an empty <vary-by-query-parameter /> to cache based on the full path.
itemId and items are invalid here, and cache-lookup-value is not applicable - it's for retrieving named values from the cache directly.
