Subject Re: SSL Offloading and Wicket

Hi,

I think you should ask in Tomcat mailing lists.
The related code in Wicket is:
https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/protocol/http/servlet/ServletWebResponse.java?source=cc#L232

As you can see Wicket always passes relative url to the underlying
container.
The container makes it absolute, i.e. sets the scheme, host, port and full
path, and then sets the "Location" response header.
