I stumbled across a site that uses multiple fragment identifiers in their URLs, like http://www.ejeby.se/#newprodukt#produkt#1075#1 (no, it is not my site, but I am linking to it, which brings problems for me).
But is this really correct? It does seem to cause problems for Safari and possibly also Internet Explorer (hearsay, I have not tried IE myself).
Isn’t the fragment identifier supposed to uniquely identify one location in the document?
Is this a bug in Safari or is it http://www.ejeby.se that uses fragment idenifiers in a wrong way?
Edit: Seems that the problem for Safari is that it escapes all # but the first in the URL. The other browsers do not do this. Correct behaviour or not?
From the specification point of view, a fragment can contain the following characters (I’ve already expanded the productions):
So, no, the fragment must not contain a plain
#; it must be encoded with%23.But it is possible that some browsers display it differently just as sequences of percent-encoded octets, that represent valid UTF-8 characters are replaced by the characters they represent.
