Randal covered off-site link tracking in his web techniques column:

AFAIK - there is no way to know for sure that a new browser window has
been opened. You could try checking the referrer field, which is typically
blank when a new window is opened, but as other threads on this list have
commented, depending on the referrer field for anything is unreliable
because browser handling of referrers is inconsistent and some proxies
destroy it altogether.

Date 20 February 2001Hi everyone,
I have to make the tracking of users who follow links to external sites
possible, preferably indicating in specific logfiles when a new browser is
opened for linking to external sites.
We have tried proxy solutions, modifying Apache core modules and are
considering scanning and parsing our Html on the fly.
I understand that uri.c could be modified or changes could be made to the
.htaccess file.
The problem is it has to be fast and transparant, does anyone have any
ideas???
Thanks in advance
Steve Smith
