<div class="jive-rendered-content"><p>To help users get started with AS7 we include a simple welcome context exposed on the JBoss Web connector, on clicking the link for the admin console we attempt a redirect after checking if we believe it is likely to succeed - this document describes the redirect scenarios and expected outcomes.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>One point to note is that the JBoss Web connector and management HTTP interface are deliberatly separate - when sending a redirect we do not want the redirect to be revealing internal server details not intended to be made public.</p><p style="min-height: 8pt;
