for the request or null
if the Url

not recognized.

null
int getCompatibilityScore(Request request)
A good criteria for calculating the score is the number of matched url segments. For example
when there are two mappers for a mounted page, one mapped to /foo
another to
/foo/bar
and the incoming request URL is /foo/bar/baz, the mapping
to /foo/bar
should probably handle the request first as it has matching segments
count of 2 while the first one has only matching segments count of 1.
Note that the method can return value greater then zero even if the mapper does not recognize the request.
