Apache module mod_usertrack

# Module mod_usertrack

Previous releases of Apache have included a module which generates a 'clickstream' log of user activity on a site using cookies. This was called the "cookies" module, mod_cookies. In Apache 1.2 and later this module has been renamed the "user tracking" module, mod_usertrack. This module has been simplified and new directives added.

## Logging

Previously, the cookies module (now the user tracking module) did its own logging, using the `CookieLog` directive. In this release, this module does no logging at all. Instead, a configurable log format file should be used to log user click-streams. This is possible because the logging module now allows multiple log files. The cookie itself is logged by using the text `%{cookie}n` in the log file format. For example:

    CustomLog logs/clickstream "%{cookie}n %r %t"

For backward compatibility the configurable log module implements the old `CookieLog` directive, but this should be upgraded to the above `CustomLog` directive.

## Directives

- CookieExpires
- CookieTracking

## CookieExpires

Syntax: CookieExpires expiry-period
Context: server config, virtual host
Status: optional
Module: mod_usertrack

When used, this directive sets an expiry time on the cookie generated by the usertrack module. The expiry-period can be given either as a number of seconds, or in the format such as "2 weeks 3 days 7 hours". Valid denominations are: years, months, weeks, hours, minutes and seconds.

If this directive is not used, cookies last only for the current browser session.

## CookieTracking

Syntax: CookieTracking on | off
Context: server config, virtual host, directory, .htaccess
Override: FileInfo
Status: optional
Module: mod_usertrack

When the user track module is compiled in, and "CookieTracking on" is set, Apache will start sending a user-tracking cookie for all new requests. This directive can be used to turn this behavior on or off on a per-server or per-directory basis. By default, compiling mod_usertrack will not activate cookies.
