view-source URI scheme
The view-source URI scheme is used by some web browsers to construct URIs that result in the browser displaying the source code of a web page or other web resource.[1]
For example, the URI view-source:http://example.com should show the source of the page located at http://example.com.
On 25 May 2011, the 'view-source' URI scheme was officially registered with IANA [2] per RFC 4395.
Browser support
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]
