Some websites may not behave as expected in Windows Internet Explorer 8 or in Windows Internet Explorer 9. This problem does not occur in earlier versions of Internet Explorer, and the affected websites continue to be displayed correctly and to work correctly in Windows Internet Explorer 7.
For example, you may experience any of the following symptoms in Internet Explorer 8 or in Internet Explorer 9:
Some websites are designed for older browsers. You may experience compatibility issues on these sites until they are updated for Internet Explorer 8 or for Internet Explorer 9.
Internet Explorer 8 and Internet Explorer 9 include a Compatibility View feature that displays websites that were created for older browsers as they were designed to appear with Internet Explorer 7. You can enable Compatibility View in Internet Explorer or on the Web server.
For general users and for advanced users
Method 1: Enable Compatibility View for specific websites in Internet ExplorerTo enable Compatibility View for specific websites that are not displayed correctly or that are not working correctly, follow these steps:
Note When you use this method to fix a website, Internet Explorer saves your Compatibility View setting for that website. Every time that you visit that site, Compatibility View will be used. To stop a website from running in Compatibility View, follow these steps:
If this method did not work, you are experiencing a different problem. See the "Similar problems and solutions and support information" section for alternative steps.

For website content developers and for website administratorsThe following information is intended for Web content developers and for website administrators. To give you time to transition your Web content to Internet Explorer 8 Standards mode, you can specify that your content should always be viewed in Compatibility View. To enable Compatibility View for your whole website, use Method 1. To enable Compatibility View for specific webpages, use Method 2.
Note When you use either of these methods, Internet Explorer 8 displays your whole site or a specific page in the same manner that Internet Explorer 7 displays the website. Specifically, Internet Explorer will render pages either in Internet Explorer 7 Standards (Strict) mode or in Internet Explorer 5 (Quirks) mode, depending on the Doctype element declaration.
These methods should address most display and functionality issues. However, your browser detection code may also have to be updated on your site.

To do this in Internet Information Services (IIS) on a Windows server-based Web server, you must either add a custom HTTP response header in IIS or configure the Web.config file for the appropriate directory.
Add the custom HTTP response header in IISTo add a custom HTTP response header at the website level, at the folder level, or at the virtual directory level in IIS, follow the steps for the version of IIS that you are using.
IIS 7 on a Windows Server 2008-based Web server
To add this header to the Web.config file, create or revise the Web.config file as follows.
Note Add this new or revised Web.config file to each Web directory in which you want to use compatibility mode.
Use the <Meta> tagTo enable Compatibility View for specific webpages, use the following <Meta> tag after the <Head> tag on the page.
This tag overrides any HTTP header declaration in the HTML for a particular webpage.
The following sample code shows how to use this Internet Explorer 7 compatibility mode tag on a per-page basis.
Important To make sure that the compatibility meta tag is used correctly, we recommend that the compatibility meta tag is positioned immediately after the <Head> tag and before any other metadata. Failure to correctly position the compatibility meta tag may cause Internet Explorer 8 to ignore the value and to continue to render in Internet Explorer 8 Standards mode.
Use HTTP response headersIf you use ASP.NET themes, use an HTTP response header to enable Compatibility View. To enable Compatibility View for an entire site, use an HTTP response header in the Global.asax file. If your site uses the Single-File Page model or the Code-Behind Page model, use an HTTP response header on each page.
