Robert Kennedy updated HTTPCLIENT-2202:
---------------------------------------
    Description: 
There appears to be a regression from 4.x to 5.x in which 
[MemcachedHttpCacheStorage|https://hc.apache.org/httpcomponents-client-5.1.x/current/httpclient5-cache/apidocs/]
 now requires the MemcachedClient object instead of the interface 
MemcachedClientIF. The class doesn't use any functionality outside of the 
interface, so why require anything higher than the interface?

Changing to use MemcachedClientIF would be backward compatible since 
MemcachedClient implements this interface already.
