View-source URI scheme
（重定向自View Source）
The view-source URI scheme is used by some browsers to construct URLs that refer to a source display for a given resource.
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 per RFC 4395.
