Question

I want to avoid that. I’ve tried:

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

(from HTML5 doctype putting IE9 into quirks mode? )
And:

<meta http-equiv=”X-UA-Compatible” content=”IE=9″ />

(from Disable quirks mode for parent frame )

But neither helps. When I do F12 – Document mode IE9 standards – the page is shown fine.

Any solution?

Answer 1

If the page is local, or on an Intranet , Internet Explorer defaults to quirks mode.

If you put the same page on The Web, it would behave as expected.

To get it working as you want, as you are using ASP.NET, you can add this to your web.config file:

<system.webServer>
<httpProtocol>
  <customHeaders>
    <clear />
    <add name="X-UA-Compatible" value="IE=edge" />
  </customHeaders>
</httpProtocol>

This avoids having to override the user settings for all Intranet pages.
