| Description: | Clickstream logging of user activity on a site |
|---|---|
| Status: | Extension |
| Module Identifier: | usertrack_module |
| Source File: | mod_usertrack.c |
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.
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.

From: "Christian Allen" <christian@sane.com> Subject: Re: Apache Y2K bug in mod_usertrack.c Date: Tue, 30 Jun 1998 11:41:56 -0400 Did some work with cookies and dug up some info that might be useful. True, Netscape claims that the correct format NOW is four digit dates, and four digit dates do in fact work... for Netscape 4.x (Communicator), that is. However, 3.x and below do NOT accept them. It seems that Netscape originally had a 2-digit standard, and then with all of the Y2K hype and probably a few complaints, changed to a four digit date for Communicator. Fortunately, 4.x also understands the 2-digit format, and so the best way to ensure that your expiration date is legible to the client's browser is to use 2-digit dates. However, this does not limit expiration dates to the year 2000; if you use an expiration year of "13", for example, it is interpreted as 2013, NOT 1913! In fact, you can use an expiration year of up to "37", and it will be understood as "2037" by both MSIE and Netscape versions 3.x and up (not sure about versions previous to those). Not sure why Netscape used that particular year as its cut-off point, but my guess is that it was in respect to UNIX's 2038 problem. Netscape/MSIE 4.x seem to be able to understand 2-digit years beyond that, at least until "50" for sure (I think they understand up until about "70", but not for sure). Summary: Mozilla 3.x and up understands two digit dates up until "37" (2037). Mozilla 4.x understands up until at least "50" (2050) in 2-digit form, but also understands 4-digit years, which can probably reach up until 9999. Your best bet for sending a long-life cookie is to send it for some time late in the year "37".
| Description: | The domain to which the tracking cookie applies |
|---|---|
| Syntax: | CookieDomain domain |
| Context: | server config, virtual host, directory, .htaccess |
| Override: | FileInfo |
| Status: | Extension |
| Module: | mod_usertrack |
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, ".foo.com" is legal, but "foo.bar.com" and ".com" are not.
| Description: | Expiry time for the tracking cookie |
|---|---|
| Syntax: | CookieExpires expiry-period |
| Context: | server config, virtual host, directory, .htaccess |
| Override: | FileInfo |
| Status: | Extension |
| 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, 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.
| Description: | Name of the tracking cookie |
|---|---|
| Syntax: | CookieName token |
| Default: | CookieName Apache |
| Context: | server config, virtual host, directory, .htaccess |
| Override: | FileInfo |
| Status: | Extension |
| Module: | mod_usertrack |
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 "-".
| Description: | Format of the cookie header field |
|---|---|
| Syntax: | CookieStyle
Netscape|Cookie|Cookie2|RFC2109|RFC2965 |
| Default: | CookieStyle Netscape |
| Context: | server config, virtual host, directory, .htaccess |
| Override: | FileInfo |
| Status: | Extension |
| Module: | mod_usertrack |
This directive controls the format of the cookie header field. The three formats allowed are:
Not all clients can understand all of these formats. but you should use the newest one that is generally acceptable to your users' browsers.
| Description: | Enables tracking cookie |
|---|---|
| Syntax: | CookieTracking on|off |
| Default: | CookieTracking off |
| Context: | server config, virtual host, directory, .htaccess |
| Override: | FileInfo |
| Status: | Extension |
| 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.
