I have recently started working on the User-Agent based shared-session protection which works between sub domains.
I am working on two sub domains first one is example.com and and second is sub.example.com
I am receiving below USER-AGENT header
“User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko”
I have done research on them from my side and able to intercept the requests to both domains and I found that surprisingly the USER-AGENT HTTP Header which was sent to each domain was different.
Is there anybody who can tell me the reason behind such strange behavior?
