I've just noticed that the long, convoluted Facebook URLs that we're used to now look like this:
As far as I can recall, earlier this year it was just a normal URL-fragment-like string (starting with
#), without the exclamation mark. But now it's a shebang or hashbang (
#!), which I've previously only seen in shell scripts and Perl scripts.
The new Twitter URLs now also feature the
#! symbols. A Twitter profile URL, for example, now looks like this:
#! now play some special role in URLs, like for a certain Ajax framework or something since the new Facebook and Twitter interfaces are now largely Ajaxified?
Would using this in my URLs benefit my Web application in any way?
