Demand: Browsing one page in a same user with more than one place(example browser or real person), URL need to be different.
As there is a team in a department, but the team is special: the team has only a user in zabbix web, so the user will be use in different computers and different browers.
My suggest: add sessionid to table "user_history" (relate to userid). Example: SELECT title1, url1, title2, url2, title3, url3, title4, url4, title5, url5 FROM user_history WHERE userid=1 and sessionid=ef7b42f9ae9c247e
