Internet Explorer 8.0 as of now Beta 2 introduces a new method of interpreting and displaying the HTML data sent from web servers. In some cases, this can result in the web pages being displayed to users incorrectly. For example the pages may display with incorrect layout, or with overlapping text and images. Unless a web site author designs their web pages with Internet Explorer 8.0's new methodology in mind, these display issues may occur.
To workaround these display issues, it is possible to make configuration changes in IIS so that special instructions are sent along with the HTTP response, telling IE8 browsers to display the data the same way IE7 would. The steps listed below show how to add the IE=EmulateIE7 HTTP header Server-Wide on both IIS 6 and IIS 7. These settings can also be changed at the site, virtual directory or any level in the configuration. The steps are included to make these changes from both the User Interface (UI) and from the command-line.
