The mod\_usertrack module in Apache is used for clickstream tracking. It helps you track a user browsing or clicking activity across your website. The user tracking is performed by using a cookie. A cookie is an alphanumeric identifier that is unique and transmitted to the client’s browser. The cookie can later be retrieved to identify the user.
Here’s how to set up mod\_usertrack:
1. First, you must enable mod_usertrack in your Apache installation. You may need to edit your httpd.conf file and remove the ‘#’ from the front of the line that begins with ‘LoadModule usertrack_module’. If that line doesn’t exist, you’ll need to add it.
1. Always back up files before making changes. The actual command to uncomment the module may be ‘LoadModule usertrack_module modules/mod_usertrack.so’
1. Once you’ve done that, you’ll then need to restart your Apache server to apply the changes. You can use the following command to restart Apache: For Ubuntu: ‘sudo systemctl restart apache2‘ For CentOS: ‘sudo systemctl restart httpd’
1. In your site’s configuration file (That could be httpd.conf, apache2.conf or any virtual host file), add the following lines
```
```
1. Issue a graceful restart to the Apache service for the changes to take effect.
Remember that you should tailor your configuration to match your own needs. The above is just an example configuration.
You may require to analyze your Apache log files to gather the tracking data. The cookie data is often appended to the end of the log entry. You can then analyze your logs using any log processing tool to see which pages your users are accessing and in what order.
Keep in mind though, that usage of such tracking methods should be clearly disclosed in your website’s privacy policy, as it could impact user privacy.
