Cross-browser support for HTML5's noreferrer link type.
HTML5 defines a new link type called "noreferrer" which may be used to annotate a hyperlink to indicate that a Referer (sic) header should not be sent when following the link.
This is particularly useful when you want to put hyperlinks to external resources on your private site which URL should not be leaked.
At the time of writing, WebKit-based browsers such as Safari, MobileSafari, Chrome and Opera 15+ already support this feature but IE, Firefox and Opera 12- do not.
noreferrer.js depends on:
- prototype.js 1.6 or later
jquery.noreferrer.js depends on:
- jQuery 1.2 or later
Chrome, Safari, MobileSafari, Opera 15+ and other WebKit-based browsers
These have native support for noreferrer links, so noreferrer.js does nothing.
noreferrer.js uses a simple meta refresh technique to suppress Referer, plus disables opening a new window with middle clicking.
There seems to be no way to prevent the browser from sending a Referer header, so noreferrer.js replaces all noreferrer links with those using Google's redirector.
Firefox and other browsers
noreferrer.js uses a data URI technique to suppress Referer, plus disables opening a new window with middle clicking.
It does not deal with dynamically created links at the moment.
Make small optimizations.
