cachedPOST function

Cache the response of a POST

Some APIs have resources where a POST is used to send a command that returns content and doesn't modify state. In this case, it's more like a GET. This may occur where one might normally GET but the request URI would be too long for the server to accept. cachedPOST thus behaves more like GET, checking for a cached response before performing the request and setting cache if the request is successful. It does no cache dropping, unlike POST().
