Referrer parsing

The Reference session agent can parse the HTTP_REFERER value in the REQ buffer into a more accessible set of name-value pairs.

Consider the following example name-value pair:


HTTP_REFERER=[http://www.yourdomain.com/parent/first_child/second_child/
              page.html?id=1234&req=25&page_id=2]

The [referrer] section in the REQ buffer looks like this:


[referrer]
REFERRER_DOMAIN=yourdomain.com
REFERRER_FILEPATH=/parent/first_child/second_child/page.html
req=25
page_id=2
id=1234

This configuration allows Tealeaf to generate events on and collect data for values within certain referring URLs of your choosing.

First Hit: The referrer parsed from the first hit of a session is used as input for the session attribute that tracks referrer values. This value is the referrer for the session.
Each Hit: The Reference session agent also detects the referrer value for each hit in the session.

To enable referrer parsing in the Reference session agent, set ReferrerParsing=True in the session agent configuration through TMS.

If ReferrerParsing is not enabled, the pattern Referrer Domain provided by Tealeaf does not capture any data.
