Apache Module mod_example_hooks

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 modexamplehooks.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.

cp modules/examples/modexamplehooks.c modules/newmodule/ modmyexample.c

modules/new_module/config.m4

. If your module doesn't need special build instructions, all you need to have in that file is include $(top_srcdir)/build/special.mk

SetHandler example-hooks-handler

After reloading/restarting your server, you should be able to browse to this location and see the brief display mentioned earlier.

directive just sets a demonstration flag which the example module's content handler displays. It takes no arguments. If you browse to an URL to which the example-hooks content-handler applies, you will get a display of the routines within the module and how and in what order they were called to service the document request. The effect of this directive one can observe under the point " Example directive declared here: YES/NO
