DotNet Postbacks Not Working in IE11

Many people are posting the woes of DotNet Postbacks not working in IE11.  I too experienced this and remembered that there were app_browser files that could be modified to give the browser further instructions.  With a quick google search I was able to find the exact solution that I was looking for.  I cannot take credit for it so I will share the original URL from which I got my answer. [ Answer ]

However Here is the code so you do not have to click on the link above:

 <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" />

     </capabilities>  
   </browser>

How to change IE11 Useragent

I recently tripped on a need to change the Useragent string for IE11 because of an older DotNet control that I was using and was no longer in development. Again this is not my solution, but it worked for me and I thought I would share it with the world. Since it is not my solution, here is the original link [ Answer ]

 <rewrite>  
 <rules>  
 <rule name="Change IE 11 User Agent to IE 10" enabled="true">  
  <match url="(.*)" />  
  <action type="None" />  
  <conditions>  
   <add input="{HTTP_USER_AGENT}" pattern=".trident\/[789]" />  
  </conditions>  
  <serverVariables>  
   <set name="HTTP_USER_AGENT" value="Mozilla/5.0 (compatible; MSIE 11.0; Windows NT 6.2; Trident/7.0)" />  
  </serverVariables>  
  </rule>  
  </rules>  
 </rewrite>

To make this work, you need to add the variable “HTTP_USER_AGENT” to the rewrite module in IIS.  If you do not, you will be told to by the error returned in IIS.  For instructions for adding the variable click the following:  [ link ]

IE11 Thinking it is a Cookieless Browser

Recently I had an issue where IE11 did not want to track cookies turning IE11 into a Cookieless Browser.  I learned quickly this is the default behaviour of the browser unless you uncheck a no-tracking option during its setup.  You know that you have an issue when you have a url that has hash like injection in it after a user signs in.  Since you cannot force your users to turn off the no-tracking option, here is a way I got around it for sites with logins.

In the code below, the key is cookieless=”UseCookies”

 <authentication mode="Forms">  
  <forms name=".AUTH" cookieless="UseCookies" loginUrl="/" timeout="10000" path="/" />  
 </authentication>
