I made a site in php and when i visit it it shows a session id in the url.
http://pandhuishaaglanden.nl/wat_wij_verkopen.php?PHPSESSID=f4d91f171d85b4ccabbb8d06e29b7308
I dont know why or how, because google sees this a duplicate content in the SEO standaards.
Can someone please tell me what or how this is.
Thats to support browsers with deactivated cookies / without cookie support. PHP also supports session authentication via URL parameter (with
session.use_only_cookiesset to0) instead of a cookie.To disable it set
session.use_trans_sidto0with ini_set. You also might wanna setsession.use_only_cookiesto1to be surePHPSESSIDin URL won’t be used at all.
