Header redirect 2. Direct entry (as above) 3. anonymous proxy filters out the headers 4. user install "Privacy-protect" software 5. The browser doesn't support it. From one of my larger sites: mysql> select count(*) from stat; +----------+ | count(*) | +----------+ | 1391545 | +----------+ 1 row in set (0.00 sec) mysql> select count(*) from stat where urlid=5343192248684061102; +----------+ | count(*) | +----------+ | 348162 | +----------+ 1 row in set (1.69 sec) mysql> select (348162 / 1391545) *100.0; +---------------------------+ | (348162 / 1391545) *100.0 | +---------------------------+ | 25.02 | +---------------------------+ 1 row in set (0.00 sec) mysql> select conv(PASSWORD('[NO REFERRING URL]'),16,10); +--------------------------------------------+ | conv(PASSWORD('[NO REFERRING URL]'),16,10) | +--------------------------------------------+ | 5343192248684061102 | +--------------------------------------------+ 1 row in set (0.00 sec) So 25% of my traffic is not sending HTTP_REFERER ...
