It seems like the engine completely breaks all links that use a URI with a scheme other than 'http' or 'https'. Web != Internet, guys! ;)

For example, the market scheme links to the Android market:
market://details?id=com.google.zxing.client.android (<-- if it worked, you'd see a link here)

I can also think of a number of relevant schemes for the Gaming SE, e.g. the steam scheme:
steam://store/400/ (<-- if it worked, you'd see a link here)
And various smaller ones which are specific to certain games to install mods, add-ons, etc.

And here's a real life example: Android SE: Is there a good app for monitoring the amount of data traffic? If this link wasn't broken, I could just click it and my phone would start installing the app or show the search results.

Looking at your post source, for completeness, I should mention that this doesn't work with either the inline or referential link syntax. –  Jon Seigel Nov 28 '10 at 16:56

We don't support any URIs other than ones we have whitelisted, which is http, https, and ftp.

Yes, that's my complaint. URI schemes are a great way to bridge over from the web to the other parts of the internet. It's a shame that this isn't supported by the SE platform. –  hheimbuerger Nov 29 '10 at 8:14

Is there a reason why these schemas are blessed, as opposed to others? Nevermind TinyURL does cross-schema redirections -- a good thing, if you ask me. –  badp Nov 29 '10 at 9:11

@radp: Of course this a) makes people less likely do link to other schemes when it makes sense (a bad thing) and it b) hides the actual link target from the reader (a very bad thing). –  hheimbuerger Dec 3 '10 at 0:11

This is indeed, frustrating. Plenty of times I have wanted SO to refer me to somewhere for live help, which is usually on an IRC channel somewhere. I don't see why irc can't be in this whitelist also. –  tudor May 24 '13 at 0:35

Is there a chance to see this being mentioned in the documentation? –  DaSourcerer Dec 14 '13 at 15:24
    
@tudor, if the solution of your question refers you to some live help, then that is useless for any future visitor. Good chance the question is off topic then. For questions and answers, I don't see why IRC should be whitelisted. –  Arjan Dec 14 '13 at 17:06

Can we have this answer revised? It feels more like an authoritative statement of policy and not so much like an explanation or line of reasoning. From a technical perspective, SO doesn't need to "support" the URI, the browsing software does. –  tudor Dec 16 '13 at 2:58
