title: JBoss EAP6 and IIS 7.5 - Cannot get connection using isapi_redirect 1.2.37, which works in JBoss 7.1.1
body: <p>I have an issue, relating to JBoss EAP 6 and IIS 7.5.</p>
  
  <p>I have a configured set up with multiple instances of JBoss EAP 6 e.g. node-a node-b etc.</p>
  
  <p>I have isapi_redirect in place to load balance between these nodes. This works successfully in JBoss 7.1.1. However when I try to run EAP 6, all I get is the following error:</p>

  <p>It does state on Redhat's website, that EAP 6 is tested up until isapi_redirect 1.2.30, but I am using isapi_redirect 1.2.37. Is this the issue?</p>
  
  <p>I'm pulling my hair out, so any help would be great. Thanks</p>
