+# This patch is required:
+# For: google authentication.
+# When: Running rails on a port other than 80 where a proxy server proxies to rails.
+# Cause: 1. Rack is not able to figure out that it should not set the realm url port to the rails custom port in case the full_host is mentioned using
+#           OmniAuth.config.full_host
+#        2. OpenID tries to validate the incoming callback url with the custom port that rails is running on and throws the error "return_to #{meth.to_s} does not match".
