This way, one can add logger hook to router, to see which "route" was taken by the request.

WSF_ROUTING_HANDLER is mainly to group a set of handler having the same base
|
|
such as /users for
|
|
/users/by/id/{id}
|
|
/users/by/name/name}
|
|
|
|
It can be used to optimize the router, where the router checks only the base path before checking each entries
|
|
Then for
|
|
/a/a1
|
|
/a/a2
|
|
/a/a3
|
|
/a/a4
|
|
/b/b1
|
|
/b/b2
|
|
/b/b3
|
|
2 routing handlers could be used "/a" and "/b"
|
|
then to find the /b/b2 match, the router has to do only
|
|
/a /b /b/b1 and /b/b2 i.e: 4 checks
|
|
instead of /a/a1 /a/a2 /a/a3 /a/a4 /b/b1 /b/b2: i.e: 6 checks
|
|
On router with deep arborescence this could be significant
