Detect Internet explorer browser version problems

asp.net, asp.net-mvc-3

Solution

The issue is the HttpBrowserCapabilities aka `Request.Browser` class parses the `userAgent` header from the request which has information about the client (in your case the browser) which might not always be 100% reliable as user agents are easily changeable.

If you know what value `MajorVersion` is returning and it's consistent enough you could possibly put a fix in for it. Alternatively you could try checking for browsers lower than IE8 instead (again though, not 100%) e.g.

@if ((Request.Browser.Browser == "IE") && ((Request.Browser.MajorVersion < 8)))
{
    //show IE7 content
}
else
{
    //show IE8+ content 
}

Problem

I have Getaway in my MVC3 application in Layout : ``` @if ((Request.Browser.Browser == "IE") && ((Request.Browser.MajorVersion == 7))) { //show some content } else { //show another content } ``` I have many users complains (users with internet explorer 8). They see Internet explorer 7 content from my app. What wrong with my way of detecting Internet explorer 7 version? How can I be sure for 100% in my application that user have internet explorer 7 version? May be this is specific OS problem?
