Force IE compatibility mode off using tags

Question

I am doing work for a client who forces compatibility mode on all intranet sites  I was wondering if there is a tag I can put into my HTML that forces compatibility mode off

Insert as the very first item under the tag.

This forces IE to render the page in the physical version of IE, and it ignores the Browser "Mode setting". This can be set in the developer tools, try changing it to a older version of IE to test, this should be ignored and the page should look exactly the same.

As suggested in this answer to a related question   edge  mode can be set in the Web Config file  This will make it apply to all HTML returned from the application without the need to insert it into individual pages    lt configuration gt       lt system webServer gt           lt httpProtocol gt               lt customHeaders gt                   lt add name  X-UA-Compatible  value  IE edge    gt               lt  customHeaders gt           lt  httpProtocol gt       lt  system webServer gt   lt  configuration gt    This same step can also be accomplished by modifying the  HTTP Response Headers  using IIS Manager for the IIS server  entire website  or specific applications

If you re working with a page in the Intranet Zone  you may find that IE9 no matter what you do  is going into IE7 Compat mode   This is due to the setting within IE Compatibility settings which says that all Intranet sites should run in compatibility mode  You can untick this via a group policy  or just plain unticking it in IE   or you can set the following    lt meta http-equiv  X-UA-Compatible  content  IE Edge    gt    This works  as detailed in other answers   but may not initially appear so  it needs to come before the stylesheets are declared  If you don t  it is ignored

This is due to the setting within IE Compatibility settings which says that all Intranet sites should run in compatibility mode  You can untick this via a group policy  or just plain unticking it in IE   or you can set the following    lt meta http-equiv  X-UA-Compatible  content  IE Edge    gt    Apparently it is not possible to change the compatibility view settings as a group policy but it is something that can perhaps be changed in the registry  this meta tag works fine for me  I had to make the required attribute work as part of a html form  it worked in chrome and firefox but not IE   Here is a nice visual of what browsers support each individual html 5 element   http   html5readiness com   Notice the one common denominator Google Chrome  it supports everything  Hope this is of help

There is the  edge  mode     lt html gt      lt head gt         lt meta http-equiv  X-UA-Compatible  content  IE edge    gt         lt title gt My Web Page lt  title gt      lt  head gt      lt body gt         lt p gt Content goes here  lt  p gt      lt  body gt   lt  html gt    From the linked MSDN page      Edge mode tells Windows Internet Explorer to display content in the highest mode available  which actually breaks the    lock-in    paradigm  With Internet Explorer 8  this is equivalent to IE8 mode  If a  hypothetical  future release of Internet Explorer supported a higher compatibility mode  pages set to Edge mode would appear in the highest mode supported by that version  however  those same pages would still appear in IE8 mode when viewed with Internet Explorer 8     However   edge  mode is not encouraged in production use      It is recommended that Web developers restrict their use of Edge mode to test pages and other non-production uses because of the possible unexpected results of rendering page content in future versions of Windows Internet Explorer    I honestly don t entirely understand why  But according to this  the best way to go at the moment is using IE 8

If you want each individual web page to load the chosen content and are using asp net  Just apply it as the first tag under the heading tag in Views shared Layout cshtml  just a tip

Just a few more notes on this topic based on my recent experiences   The university I work for issues laptops with IE 8 set to compatibility mode for all Intranet Sites   I tried adding the meta tag to disable this mode for pages being served up by my site but IE consistently ignored this tag   As Lance mentioned in his post  adding a response header fixed this issue   This is how I set the header based on the HTML5 boilerplate method    lt IfModule mod headers c gt    Header set X-UA-Compatible  IE edge chrome 1      mod headers can t match by content-type  but we don t want to send this header on  everything        lt FilesMatch     appcache crx css eot gif htc ico jpe g js m4a m4v manifest mp4 oex oga ogg ogv otf pdf png safariextz svg svgz ttf vcf webm webp woff xml xpi    gt      Header unset X-UA-Compatible    lt  FilesMatch gt   lt  IfModule gt    In order for this header to actually be sent  you have to make sure you have mod headers turned on in Apache   If you want to make sure you have this mod turned on  put this in a page that can run php    lt pre gt   lt  php     print r apache get modules       gt   lt  pre gt

After many hours troubleshooting this stuff    Here are some quick highlights that helped us from the X-UA-Compatible docs   http   msdn microsoft com en-us library cc288325 VS 85  aspx ctl00 contentContainer ctl16  Using  lt meta http-equiv  X-UA-Compatible  content                gt    The Standard User Agent modes  the non-emulate ones  ignore  lt  DOCTYPE gt  directives in your page and render based on the standards supported by that version of IE  e g   IE 8 will better obey table border spacing and some pseudo selectors than IE 7     Whereas  the Emulate modes tell IE to follow any  lt  DOCTYPE gt  directives in your page  rendering standards mode based the version you choose and quirks mode based on IE 5 Possible values for the content attribute are   content  IE 5    content  IE 7   content  IE EmulateIE7   content  IE 8   content  IE EmulateIE8   content  IE 9   content  IE EmulateIE9   content  IE edge

IE8 defaults to standards mode for the intERnet and quirks mode for the intRAnet  The HTML meta tag is ignored if you have the doctype set to xhtml transitional  The solution is to add an HTTP header in code  This worked for us  Now our intranet site is forcing IE8 to render the app in standards mode   Added to PageInit of the base page class  ASP net C     Response AddHeader  X-UA-Compatible    IE EmulateIE8      reference  http   ilia ws archives 196-IE8-X-UA-Compatible-Rant html

If you have access to the server  the most reliable way of doing this is to do it on the server itself  in IIS  Go in to IIS HTTP Response Headers   Add  Name  X-UA-Compatible Value  IE edge This will override your browser and your code
