Logging

mod_usertrack sets a cookie which can be logged via mod_log_config configurable logging formats:

LogFormat "%{Apache}n %r %t" usertrack
CustomLog logs/clickstream.log usertrack

CookieDomain Directive

This directive controls the setting of the domain to which the tracking cookie applies. If not present, no domain is included in the cookie header field.

The domain string must begin with a dot, and must include at least one embedded dot. That is, .example.com is legal, but www.example.com and .com are not.

CookieDomain .example.com

CookieExpires Directive

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, days, hours, minutes and seconds. If the expiry time is in any format other than one number indicating the number of seconds, it must be enclosed by double quotes.

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

CookieExpires "3 weeks"

CookieName Directive

This directive allows you to change the name of the cookie this module uses for its tracking purposes. By default the cookie is named "Apache".

You must specify a valid cookie name; results are unpredictable if you use a name containing unusual characters. Valid characters include A-Z, a-z, 0-9, "_", and "-".

CookieStyle Directive

This directive controls the format of the cookie header field. The three formats allowed are:

• Netscape, which is the original but now deprecated syntax. This is the default, and the syntax Apache has historically used.
• Cookie or RFC2109, which is the syntax that superseded the Netscape syntax.
• Cookie2 or RFC2965, which is the most current cookie syntax.

Not all clients can understand all of these formats, but you should use the newest one that is generally acceptable to your users' browsers. At the time of writing, most browsers support all three of these formats, with Cookie2 being the preferred format.

CookieTracking Directive

When mod_usertrack is loaded, and CookieTracking on is set, Apache will send 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, enabling mod_usertrack will not activate cookies.
