The mod_cidr_lookup is an Apache module for version 2.2 and 2.0. The mod_cidr_lookup detects client type by looking up the client's source IP address in CIDR blocks. This module sets the environment variable X_CLIENT_TYPE and the HTTP request header X-Client-Type, so it can be used in both Apache (httpd.conf) and Web applications.
