Site URLs vary despite same semantics

[etj]

This is because the CGI variables are emitted in a random order - I expect there's a `keys` call.

I believe it would be better to sort those, so that semantically identical URLs with CGI args will always have the same canonical "spelling", so one can most easily see at a glance whether one has previously visited them.

I have no idea what this post is about. Can you give an example?

He's referring to the fact that
/index.pl?node_id=3184;displaytype=raw;ticker=yes
and
/index.pl?node_id=3184;ticker=yes;displaytype=raw
are logically identical.
