Keep in mind that Lift's behavior for 404s differs between development and
production mode in Lift 1.1-xxx
To have your app/Lift handle a 404 rather than passing it to your web
container, in Boot.scala:
LiftRules.passNotFoundToChain = false
LiftRules.uriNotFound.prepend {
case _ => XhtmlResponse((<html> <body>Silly goose</body> </html>),
Empty, List("Content-Type" -> "text/html;
charset=utf-8"), Nil, 404, S.ieMode)
}
In development mode, Lift will tell you about SiteMap as this was a common
confusion point among new developers. In production mode, Lift will use
that code. To put Lift in production mode:
mvn -Drun.mode=production jetty:run
I would strongly recommend against a "catch-all" entry in SiteMap as it will
expose every page on your site to access.
