My website is broken in IE11.
We all know that HTML tags allow developer to force IE compatibility mode; in example
<meta http-equiv="X-UA-Compatible" content="IE=8, IE=9" />
worked great and solved the visualization problems for IE10.
But actually on IE11, even if Compatibility mode
is set to IE9
, User agent string
is set to default
and javascript doesn't work.
Changing manually User agent string
to IE10
solved my problems.
For shure I'm going to solve the real problems that cause website errors, but actually I need a fast, programatic way to force "User agent string" to IE10, since I can't contact every user.
Can someone help?
Microsoft Edge and Internet Explorer To open them, click the settings menu and select “F12 Developer Tools” or just press F12 on your keyboard. The developer tools will open in a separate pane at the bottom of the window. Click the “Emulation” tab and choose a user agent from the “User agent string” box.
A browser's User-Agent string (UA) helps identify which browser is being used, what version, and on which operating system. When feature detection APIs are not available, use the UA to customize behavior or content to specific browser versions.
Because the Netscape browser initially implemented many features not available in other browsers and quickly came to dominate the market, a number of web sites were designed to work, or work fully, only when they detected an appropriate version of Mozilla in the user agent string.
I also faced the same problem in my 2003 windows server with .net framework 4.0 and after a long research i found the below is helpful...
I created App_Browsers folder and put a browser file named as ie.browser and pasted the below browser definition text and it started working
<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>

Solved! Website is up just installing Dotnet framework 4.5 on server
Actually I didn't find a way to force programmatically browsers User agent string (this was the original question). But repaired website with 0 code..
Just made lot of tests and on one server I found out that website was working, on other server it wasn't.
The "good server" was a Win2012, and "bad servers" were Win2008. On Win2012 Aspnet 4.5 was running, and on Win2008 it wasn't.
I installed dotnet framework 4.5 on bad servers too, and everything started working!
