I have a client who gets browser script errors with our application. In troubleshooting, I see that the User Agent reported contains a couple of entries I don’t recognize:
User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; BO1IE8_v1;ENUS)
Specifically, what does BO1IE8_v1;ENUS indicate?
This is Internet Explorer 8.
Personally, I encourage users of IE8 to either upgrade to IE9 or Firefox 15.
IE8 has many, many rendering problems and security risks.
