The Apache request object implements a huge number of methods. To help you find the method you're looking for, we've broken them down into eight broad categories:
Client request methods
Methods that have to do with retrieving information about the current request, such as fetching the requested URI, learning the request document's filename, or reading incoming HTTP headers.
Server response methods
Methods that are concerned with setting outgoing information, such as setting outgoing headers and controlling the document language and compression.
Sending data to the client
Methods for sending document content data to the client.
Server core functions
Methods that control key aspects of transaction processing but are not directly related to processing browser data input or output. For example, the subrequest API is covered in this section.
Server configuration methods
Methods for retrieving configuration information about the server.
Methods for logging error messages and warnings to the server error log.
Access control methods
Methods for controlling access to restricted documents and for authenticating remote users.
Methods that use special features of mod_perl which have no counterpart in the C API. They include such things as the gensym() method for generating anonymous filehandles and set_handlers() for altering the list of subroutines that will handle the current request.
