* Answers "does the request-path path-match a given cookie-path?" as per {@link https://www.rfc-editor.org/rfc/rfc6265.html#section-5.1.4 | RFC6265 Section 5.1.4}.
|

* This is essentially a prefix-match where cookiePath is a prefix of reqPath.

|

|
|
* A request-path path-matches a given cookie-path if at least one of
|
||
|
|
* the following conditions holds:
|
||
|
|
*
|
||
|
|
* - The cookie-path and the request-path are identical.
|
||
|
|
* - The cookie-path is a prefix of the request-path, and the last character of the cookie-path is %x2F ("/").
|
||
|
|
* - The cookie-path is a prefix of the request-path, and the first character of the request-path that is not included in the cookie-path is a %x2F ("/") character.
