Migration of Apache mod_rewrite Rules to 
Advanced Policies
The Apache HTTP Server provides an engine known as mod_rewrite for 
rewriting HTTP request URLs. If you migrate the mod_rewrite rules from 
Apache to the NetScaler, you boost back-end server performance. In addition, 
because the NetScaler typically load balances multiple (sometimes thousands of) 
Web servers, after migrating the rules to the NetScaler you will have a single 
point of control for these rules.
This appendix provides examples of mod_rewrite functions, and translations of 
these functions into Rewrite and Responder policies on the NetScaler.
