When logged into the Admin of Expression Engine, and then visiting the front of the site, sometimes the URL contains an S followed by lots of characters, like this:
www.mydomain.com/S=12a33f9e958c5a998383ba60cd1539210d1fb668/my-page
I recently found out Google has indexed a page on my site containing this URL and I wondered if anyone knows why, as this is obviously quite bad.
I noticed User Session Type was set to Session, so I changed that to Cookies, but I am just concerned about how Google indexed it with the session ID.
