Need a list of - What a web server can see from a user browser session

When a web browser session starts and then ends, what information can the webserver find from the user. I need a list. There are obvious ones, like IP address, Country, Browser Type. Less obvious ones like Computer Mac Address, Browser Version, exit page. I'd like a complete list from a sys admin who runs servers as to what the possible list is of what servers can see of the user browser session. No exclusions. For a professional, this is an easy project.
