I see. I am not familiar with DNT implementation, but is there a www browser to define navigator.doNotTrack as the value "false"? If so, I think something like the following is needed. var dnt = window.navigator.msDoNotTrack || window.navigator.doNotTrack; var allow_track = (dnt && dnt == 'yes'|| dnt == 1); -- Hiroki ----Security_Multipart(Fri_Jun__7_09_25_34_2013_889)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (FreeBSD) iEYEABECAAYFAlGxKH4ACgkQTyzT2CeTzy3S5ACfeEXbxu/CzurKRi/LyR/NRxUC mrAAn1lcQvMB39W6dGKijBipcE1qR5Dk =ekzz -----END PGP SIGNATURE----- ----Security_Multipart(Fri_Jun__7_09_25_34_2013_889)----
