[ajaysinghj8]

Key Generation should be changed:

Current Implementation

-> ACP:<NAMESPACE>:<sha256 HEX of (PATH + (? - HEADERS joined with | ) + (? queryString) >

Should be

-> ACP:<NAMESPACE>:(HEX of PATH): (HEX  of (? - HEADERS joined with | ) + (? queryString)) 

Benefits-

All cache keys version of a URL can be purged based on pattern match, regardless of query-string or headers.

In order to understand the context better. I can choose to purge a specific key
/articles/asia/india/elections-2019.html

or I can choose to purge a pattern based key
/articles/asia/india
this implies to purge all articles related to india.
