Tomcat
From Sage CRM Knowledge Base
Troubleshooting:
1. Ensure parent paths is set to true for ASP
ISAPI Rewriting
1. Sage use a file called "....Sage\CRM\Services\IISUtils\CRMRewriter\ISAPI_Rewrite.dll" which is created by "Helicon" (http://www.isapirewrite.com/)
2. The rewriting rules are written in "....Sage\CRM\Services\IISUtils\CRMRewriter\CRM.Rewriter.rules"
3. Re-writing essentially maps urls such as "http://localhost/sdata/crm71sp2j/layout/-/$service/" to "http://localhost:10009/crm71j/..etc". So you can see that the port is 10009 and this is the port that TOMCAT is working through.
