Apache Module mod_example_hooks

Available Languages:  en  |  fr  |  ko 

Description:Illustrates the Apache module API
Module Identifier:example_hooks_module
Source File:mod_example_hooks.c


The files in the modules/examples directory under the Apache distribution directory tree are provided as an example to those that wish to write modules that use the Apache API.

The main file is mod_example_hooks.c, which illustrates all the different callback mechanisms and call syntaxes. By no means does an add-on module need to include routines for all of the callbacks - quite the contrary!

The example module is an actual working module. If you link it into your server, enable the "example-hooks-handler" handler for a location, and then browse to that location, you will see a display of some of the tracing the example module did as the various callbacks were made.

Support Apache!

Compiling the example_hooks module

To include the example_hooks module in your server, follow the steps below:

  1. Run configure with --enable-example-hooks option.
  2. Make the server (run "make").

To add another module of your own:

  1. cp modules/examples/mod_example_hooks.c modules/new_module/mod_myexample.c
  2. Modify the file.
  3. Create modules/new_module/config.m4.
    1. Add APACHE_MODPATH_INIT(new_module).
    2. Copy APACHE_MODULE line with "example_hooks" from modules/examples/config.m4.
    3. Replace the first argument "example_hooks" with myexample.
    4. Replace the second argument with brief description of your module. It will be used in configure --help.
    5. If your module needs additional C compiler flags, linker flags or libraries, add them to CFLAGS, LDFLAGS and LIBS accordingly. See other config.m4 files in modules directory for examples.
  4. Create module/new_module/Makefile.in. If your module doesn't need special build instructions, all you need to have in that file is include $
