View-source URI scheme
Introduction 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.For example, the URI '''view-source:''' should show the source of the page located at  https://example.com.In the early internet, View Source helped people to create their own web pages, learning by example.On 25 May 2011, the 'view-source' URI scheme was officially registered with IANA 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. Firefox also suffered a similar security issue (by combining view-source and javascript URIs), but still supported it in Firefox 1.5 after being fixed. In 2009 a new discovered bug was fixed in Firefox 3.0.9.Browser  Supported?Mozilla Firefox   SeaMonkey   Netscape   Internet Explorer 4, 5 and 6   Internet Explorer 6, 7, and 8   after Windows XP SP2 Safari 3.2.1   Safari 5, 6   Opera 7, 8, 9, 10, 11   Opera 15 and up   Google Chrome   Web   HP webOS   (Internalz Pro)
