I have a site that is nearly all standards compliant, and expects to be that way across all browsers. However, I have a specific page on my site that I want to render in a standards compliant way in Firefox, Chrome, Opera, and Safari, but due to a very annoying issue involving Zoom Levels in the Microsoft SSRS Report Viewer 10.0.0.0 control (See here for a more complete description), I need to render the page in Compatibility View mode in IE9.
For IE9, add <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />
or add <?xml version="1.0" encoding="UTF-8">
as first line in your page. See http://webdesign.about.com/od/metataglibraries/p/x-ua-compatible-meta-tag.htm for details.
