1 Introduction to vmod-dbrw

Vmod-dbrw is a module for Varnish Cache1 which implements database-driven rewrite rules. These rules may be similar to RewriteRule directives implemented by mod_rewrite2 module in Apache or to Redirect directives of its mod_alias module. What distinguishes the vmod-dbrw rules from these, is that they are handled by Varnish, before the request reaches the httpd server, and that they are stored in an SQL database, which makes them easily manageable.

Some web sites implement thousands of rewrite rules. The purpose of this module is to facilitate deploying and handling them.
