When using Bot Defense profile, if a browser page remains open too long (more then 24 hours) without surfing the webserver, BIG-IP raises an Anomaly "Invalid Bot Defense Cookie" and mitigate the request.


Clients are mitigated by this anomaly.


-- Bot Defense Profile is attached to VS. -- Browser remains open for more then 24 hours without surfing the site (after first surfing to the site)


Add Exception for "Invalid Bot Defense Cookie" to "Captcha" - clients will have to solve captcha, but cookies will renew and issue would be solved (no more Captchas)
