IE10 User-Agent causes ASP.Net to not send back Set-Cookie (IE10 not setting cookies)

Solution 1:

The problem rests with some IIS instances thinking that IE10 is a cookieless browser (i.e. cant support cookies). In our problem case the server was setting the authentication cookie and sending it back to the browser, but was then ignoring the cookie on subsequent requests.

The solution is to either patch the browser capabilities so that it knows IE10 can do cookies (outlined in another answer on this page), or change the default behaviour to force it to use cookies even if it thinks the browser can’t do cookies.

We just added the following to our forms section in web.config:

cookieless="UseCookies"

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

Solution 2:

Found this entry on MS Connect, the behavior is a recognized bug.

Suggested Workaround (from the entry):

== Workaround ==

In the meantime to make it work and to avoid similar issues in the future, I use a file ~\App_Browsers\BrowserFile.browser with the following:

<browsers>
<browser refID="Default">
<capabilities><!-- To avoid wrong detections of e.g. IE10 -->
<capability name="cookies" value="true" />
<capability name="ecmascriptversion" value="3.0" />
</capabilities>
</browser>
</browsers>

There is a hotfix available for this issue[1].

Also, [2] suggests that this will hit Windows Update in January of 2012.

Thanks You for the Help. It worked no.

I copied the file from the site to C:\WINDOWS\microsoft.net\Framework\v2.0.50727\CONFIG\Browsers
Run In Command Prompt C:\WINDOWS\microsoft.net\Framework\v2.0.50727>aspnet_regbrowsers.exe -i
Restart the IIS.
Tested the site and it works without any error.

Thanks Again for the Feed back

An update for nullptr answer.

I tried today to download the Microsoft KB2600088. After receiving the link by email, I clicked on it then it lead me the page that says it is no longer available.

Try this: http://support.microsoft.com/kb/2600217

That link is a replace ment for KB2600088 and KB2628838.

MIcrosoft .Net Framework 4.5 is also available now.
