restlet may be querying DNS for no reason - https://github.com/restlet/restlet-framework-java/issues/445
I have 1 tomcat instance which contains cas, war1 and war2.
I will see the delay when user jumps from war1 -> war2 ( war2 makes a
restlet callback to war1 ).
The problem goes away when I bring up my vpn ( can now access
additional name servers ).
Which leads me to "something is doing DNS lookups".
My debug code:
log.trace( "RESTLET - HTTPPOST - PRIOR - " + url );
org.apache.http.HttpResponse response = httpclient.execute( httppost );
log.trace( "RESTLET - HTTPPOST - AFTER - " + url );
My trace logs will show:
