function is_host_in_noproxy in Auth0 Single Sign On 8.2

Returns true if the provided host matches any of the no proxy areas.

This method will strip a port from the host if it is present. Each pattern can be matched with an exact match (e.g., "foo.com" == "foo.com") or a partial match: (e.g., "foo.com" == "baz.foo.com" and ".foo.com" == "baz.foo.com", but ".foo.com" != "foo.com").

Areas are matched in the following cases: 1. "*" (without quotes) always matches any hosts. 2. An exact match. 3. The area starts with "." and the area is the last part of the host. e.g. '.mit.edu' will match any host that ends with '.mit.edu'.

Parameters

string $host Host to check against the patterns.:

array $noProxyArray An array of host patterns.:
