/**
* Concrete implementation of {@link PortResolver} that obtains the port from
* ServletRequest.getServerPort()
.This class is capable of handling the IE bug which results in an
* incorrect URL being presented in the header subsequent to a redirect to a different scheme and port where the port
* is not a well-known number (ie 80 or 443). Handling involves detecting an incorrect response from
* ServletRequest.getServerPort()
for the scheme (eg a HTTP request on 8443) and then determining the
* real server port (eg HTTP request is really on 8080). The map of valid ports is obtained from the configured {@link
* PortMapper}.
