App_Browsers definition file for IE 11

Question

This is the user agent for IE 11 on Windows 8.1 (Preview)

 Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; Touch; rv:11.0) like Gecko

I am looking for a .browser file for either the App_Browsers folder in my application or c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\Browsers to properly detect IE11.

Since the user agent changed from containing "MSIE" such as this IE10 user agent

 Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0; Touch)

I have tried about 100 variations with no success.

Answer 1

I created a file containing

<browsers>

    <browser id="IE11" parentID="Mozilla">
        <identification>
            <userAgent match="Trident\/7.0; rv:(?'version'(?'major'\d+)(\.(?'minor'\d+)?)(?'letters'\w*))(?'extra'[^)]*)" />
            <userAgent nonMatch="IEMobile" />
        </identification>
        <capture>
            <userAgent match="Trident/(?'layoutVersion'\d+)" />
        </capture>
        <capabilities>
            <capability name="browser" value="IE" />
            <capability name="layoutEngine" value="Trident" />
            <capability name="layoutEngineVersion" value="${layoutVersion}" />
            <capability name="extra" value="${extra}" />

            <capability name="version" value="${version}" />
        </capabilities>
    </browser>

    <!-- Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11,0) like Gecko -->
    <browser id="IE110" parentID="IE11">
        <identification>
            <capability name="majorversion" match="11" />
        </identification>
        <capabilities>

            <capability name="supportsCallback" value="true" />
            <capability name="supportsFileUpload" value="true" />
            <capability name="supportsMultilineTextBoxDisplay" value="true" />
            <capability name="supportsMaintainScrollPositionOnPostback" value="true" />

            <capability name="supportsXmlHttp" value="true" />
            <capability name="tables" value="true" />
            <capability name="supportsAccessKeyAttribute" value="true" />
            <capability name="tagwriter" value="System.Web.UI.HtmlTextWriter" />
            <capability name="vbscript" value="true" />
        </capabilities>
    </browser>

</browsers>

and it worked for me. Based on answer by Sistemas-infoe on this question: doPostback failing in IE 11+ Windows 8.1
