Hi All,
We are trying to add response caching as a default feature in API Manager
using Cache mediator. There, we found that Cache mediator could handle only
SOAP-1.1 or SOAP-1.2 messages.
- If backend returns a POX response, it throws the following exception [1]
when request is served from the cache.
- If backend returns a JSON response, and once the response get added to
cache, client does not receive a response until cache expires. (No backend
errors)
Is it possible to fix those for API Manager-1.6.0 release ?
