Redirect Loop with RDM on Tomcat

Problem

In some cases, after restarting the server, re-accessing RDM results in a redirect loop.

A quick workaround is to clear the cookies.

Solution

The problem is caused by a default Tomcat setting, which keeps session IDs between restarts and causes the redirect loop in RDM.

Open tomcat/conf/context.xml and uncomment the <Manager pathname="" /> line:

<Context>
	...
    <Manager pathname="" />
	...
</Context>
