Detailed Description

These functions are responsible for allowing or denying a request, based on a number of different parameters. These parameters include the client's IP address, the hostname of the requested resource, the request method, etc. Some of the necessary information may not be immediately available, for example the origin server's IP address. In these cases, the ACL routines initiate lookups for the necessary information and continues the access control checks when the information is available.
