| * Used when switching between normal/insecure (HTTP) and secure (HTTPS) mode. When a switch occurs, it is no longer |
| * possible to use relative URLs, instead absolute URLs must be generated. The default implementation of this is |
| * simple-minded: it just tacks the correct scheme in front of {@link org.apache.tapestry5.services.Request#getServerName()}. |
| * In production, behind a firewall, it is often necessary to do a bit more, since <code>getServerName()</code> will |
| * often be the name of the internal server (not visible to the client web browser), and a hard-coded name of a server |
| * that <em>is</em> visible to the web browser is needed. Further, in testing, non-default ports are often used. In |
| * those cases, an overriding contribution to the {@link org.apache.tapestry5.services.Alias} service will allow a custom |
| * implementation to supercede the default version. |
