View-source URI scheme

The view-source URI scheme is used by some browsers to construct URLs that refer to a source display for a given resource.^[1]

For example, this URI would show the source of the page located at http://www.example.com: view-source:http://www.example.com

On 25 May 2011 the 'view-source' URI scheme was officially registered with IANA ^[2] per RFC 4395.

Browser Support

Mozilla Firefox and Internet Explorer both supported the scheme, but support was dropped from Internet Explorer in Windows XP SP2 due to security problems.^[3] Firefox also suffered a similar security issue (by combining view-source and javascript URIs^[4]), but still supported it in Firefox 1.5^[5] after being fixed. In 2009 a new discovered bug was fixed in Firefox 3.0.9.^[6]
