Everything you could ever want to know (and more) about controlling the Referer header image/svg+xml

HTML5 added a whole bunch of useful new values for the rel attribute, one of which is noreferrer (yes, spelt correctly this time). When this attribute is added, the browser is instructed not to set the header if the user follows the link. Support for this was first added to WebKit (Chrome/Safari) way back in 2009, arrived in Firefox in late 2014 and most recently was added to Microsoft Edge (but is not supported in any version of Internet Explorer).

Interesting, I was not aware of this attribute. It’s a shame about Internet Explorer’s lack of support as I could have used it as a replacement for the Unbubble derefer service that I’ve been using.

I’m looking forward to a time when IE is nothing but a distant memory.

Unbubble Derefer-Service image/svg+xml

Unbubble utilizes a derefer service to remove the referrer field from HTTP headers. This ensures the search query and referring domain is removed and not sent to any external website. The dereferrer is actually an unplanned byproduct of our safe and neutral search engine

You may use our derefer service for own purposes e.g. to obfuscate the origin of links in forums or your own blog. To conceal your links just prepend “” to any URL.

I’ve been looking for a free derefer service for a project I’m working on and found this. I’ve not used Unbubble before, but their derefer service looks better than all the others I found — I’m not sure why, but the alternatives looked dodgy/untrustworthy.

I suppose I could always create my own service, it would only take 5 minutes, but then I would have to maintain it, and I’d rather not. I’ll give the Unbubble service a try first and if it proves to be unreliable, I’ll reconsider building my own.

Also, I did think that DuckDuckGo might have a derefer service, but I couldn’t find one, which is a shame as I think one would compliment their existing services.
