### Apache HTTP Server Version 1.3

# Module mod_example

This module is contained in the `modules/mod_example.c` file, and is not compiled in by default. It illustrates many of the aspects of the Apache 1.2 API and, when used, demonstrates the manner in which module callbacks are triggered by the server.

## Summary

The files in the `src/modules/example 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.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-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.

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

1. Uncomment the "AddModule modules/example/mod_example" line near the bottom of the `src/Configuration` file. If there isn't one, add it; it should look like this:

            AddModule modules/example/mod_example.o

2. Run the `src/Configure` script ("`cd src; ./Configure`"). This will build the Makefile for the server itself, and update the `src/modules/Makefile` for any additional modules you have requested from beneath that subdirectory.
3. Make the server (run "`make`" in the `src` directory).

To add another module of your own:

1. `mkdir src/modules/mymodule`
2. `cp src/modules/example/* src/modules/mymodule`
3. Modify the files in the new directory.
4. Follow steps [1] through [3] above, with appropriate changes.

### Using the `mod_example` Module

To activate the example module, include a block similar to the following in your `srm.conf` file:

       <Location /example-info>
           SetHandler example-handler
       </Location>

As an alternative, you can put the following into a `.htaccess` file and then request the file "test.example" from that location:

       AddHandler example-handler .example

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

## Directives

- Example

## Example

Syntax: Example
Default: None
Context: server config, virtual host, directory, .htaccess
Override: Options
Status: Extension
Module: mod_example
Compatibility: `Example` is only available in Apache 1.2 and later.

The `Example` directive activates the example module's content handler for a particular location or file type. It takes no arguments. If you browse to an URL to which the example 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.
