Introducing modern.IE - A new set of tools to help you support modern and older versions of Internet Explorer

Charles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet. This includes requests, responses and the HTTP headers (which contain the cookies and caching information).

By default, all popular Web browsers assume the HTTP protocol. In doing so, the software prepends the 'http://' onto the requested URL and automatically connect to the HTTP server on port 80. Why then do many pages explictly set http on all hypertext links? Surely it is easier to type "domain.com" than "http://domain.com". HTTP is also deprecated due to the ever-evolving web: The HyperText Transfer Protocol is no longer used to transfer hypertext. It is increasingly becoming used a means to transfer any content over port 80. Thus the definition "http" no longer means anything in the context of a URL since you are unlikely to be requesting hypertext. As the web evolves, next generation protocols will begin to replace http. By explicitly using "http://domain.com" in your links you are forcing your viewers of the future into using an obsolete protocol. By using "//domain.com" you will guarantee the protocol of tomorrow will work with your pages of today. Succinctly, use of the http protocol is redundant and time consuming to communicate. The internet, media, and society are all better off without it.

IE NetRenderer allows you to check how a website is rendered by Internet Explorer 9, 8, 7, 6 or 5.5, as seen from a high speed datacenter located in Germany. Just type in a URL in the field above and try it out - it's free!

Spin.js uses the CSS3 to render the UI, falling back to VML Internet Explorer. If supported by the browser, @keyframe rules are used to animate the spinner. The spin() method creates the necessary HTML elements and starts the animation. If a target element is passed as argument, the spinner is added as first child and horizontally and vertically centered.

"If like me you have Firefox set as your default browser in Windows but need to create a desktop shortcut to a web page but force it to open in Internet Explorer or any other non-default browser there are two methods to achieve this."

There are several bugs in Internet Explorer that can be worked around by forcing "a layout" (an IE internal data structure) on an element (like, dimensional bug fixes and Holly hack). Most users are not aware of the implications of having "a layout" applied to an element. This document explains what happens when an element has a layout and what implications that has

"CSS3 PIE supports only shorthand properties (border-radius: 5px 5px 0 0;), not the longhand ones (border-radius-topleft: 5px; etc.)."

CSS3 PIE is a .htc file that faithfully recreates css3 styling in early versions of internet explorer. Simply adding "behavior: url(path/to/PIE.htc);" at the end of the selectors scope that contains the CSS3 rule causes it to render correctly in otherwise unsupported versions of IE.
