132

|
|
=head2 GOAL |
133
|
|
|
|
|
|
|
|
134
|
|
|
|
|
|
|
Server-side web hits tracking, generic and flexible enough so that |
135
|
|
|
|
|
|
|
many tracking services like Google Analytics, Piwik, local file, etc. |
136
|
|
|
|
|
|
|
can be used depending on configuration. |
137
|

|
=head2 VISION |
139
|
|
|
|
|
|
|
|
140
|
|
|
|
|
|
|
Universal enough to process many sources (headers, logs, tracking URL-s, ...) |
141
|
|
|
|
|
|
|
and covert or relay them to different other destinations (GA, Piwik, ...) |
142
|
|
|
|
|
|
|
making use of the fact that the tracking data information is the same or |
143
|
|
|
|
|
|
|
nearly the same for all the sources and destinations. |
144
|

|
|
|
|

145

|
|
|
|
|
|
=head2 IMPLEMENTATION |
146
|
|
|
|
|
|
|
|
147
|
|
|
|
|
|
|
Initially tracking data needs to be gathered. Look at L<WWW::Tracking::Data> |
148
|
|
|
|
|
|
|
for the complete list. Most of these data can be found in headers of the |
149
|
|
|
|
|
|
|
http request. Then these data can be serialized and passed on to one of |
150
|
|
|
|
|
|
|
the tracking services. |
151
|
|
|
|
|
|
|
|
152
|
|
|
|
|
|
|
Bare L<WWW::Tracking::Data> offers just C<as_hash> and C<from_hash>, the |
153
|
|
|
|
|
|
|
rest can be done by one or more plugins, like for example parsing the |
154
|
|
|
|
|
|
|
http headers with L<WWW::Tracking::Data::Plugin::Headers> and passing it |
155
|
|
|
|
|
|
|
to L<WWW::Tracking::Data::Plugin::GoogleAnalytics>. |
