Hi,

In my application, in web.config i added  below code to work in IE 10 and IE11 with IE 8 compatibility mode.

under <system.web> section i added below code

<browserCaps>
<case match="IE[ /](?'version'(?'major'\d+)(?'minor'\.\d+)(?'letters'\w*))">
browser=IE
version=${version}
majorversion=${major}
minorversion=${minor}
frames=true
tables=true
cookies=true
javascript=true
javaapplets=true
activexcontrols=true
ecmascriptversion=1.5
vbscript=true
backgroundsounds=true
isMobileDevice="true"
<filter match="[4-9]" with="${major}">
ecmascriptversion=1.3
css1=true
css2=true
xml=true
<filter match="[5-9]" with="${major}">
w3cdomversion=1.0
</filter>
</filter>
<filter match="^b" with="${letters}">
beta=true
</filter>
</case>
</browserCaps>

 under system.webServer

<httpProtocol>
<customHeaders>
<clear />
<add name="X-UA-Compatible" value="IE=8" />
</customHeaders>
</httpProtocol>

This is working in DEV environment, but in my QA environment it throwing below error

The error looks something like this:

Server Error in ‘/’ Application.
