view-source URI scheme

From HandWiki

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:https://example.com 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.[2]

On 25 May 2011, the 'view-source' URI scheme was officially registered with IANA[3] 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.[4] Firefox also suffered a similar security issue (by combining view-source and javascript URIs[5]), but still supported it in Firefox 1.5[6] after being fixed. In 2009 a new discovered bug was fixed in Firefox 3.0.9.[7]
