isInNonProxyHosts

public static Boolean isInNonProxyHosts(String targetHost)

The target hostname input is compared with the hosts in the '|' separated list provided by the http.nonProxyHosts parameter using regex. The nonProxyHosts will be used as our Patterns, so we need to replace the '.' and '*' characters since those are special regex constructs that mean 'any character,' and 'repeat 0 or more times.'
