Configuration Routines

Configuration routines include all redirector-related configuration hook functions and the Apache-specific data structures describing the module. The most important directives have been discussed above in Section 3.2 and for this reason are not repeated here. What is worth mentioning, however, is that one of the general configuration hooks, called ``post_config,'' is used. It is the best place to create all internal data structures of the redirector, since at this point the complete redirector configuration is known, and Apache has not yet started processing the client requests. Therefore, in the ``post_config'' hook function we initialize the replica database and create a special lock protecting the UDP socket (see below).
