thank you for your answer.
choose the render site in Compatibility View ,the User-Agent string can be "
Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.3; Trident/7.0;.NET4.0E; .NET4.0C)" ,but the problem is not solved,the view
of page is also different when visit by ip address and computer name, what I hope is solve this problem not by changing the setting
of ie11 ,by changing server setting or by coding can be a better way to solve this problem.
Expect your reply,Thank you.
