The rest is probably better than that bit...

Anyway... I tried that string, and a few other variations, in NetScape.  
I don't trust NetScape to exhibit "normal" behavior, but it didn't do what
you suggested.  When I entered "http://jcifs%2Esamba.org/" it popped up a
message saying:

        Netscape is unable to locate the server jcifs%2Esamba.org

...which, I think is the wrong thing to do.  The escapes should be
translated before the name is passed to the DNS query.

Regarding my example: jcifs%2Esamba.org

The dot character is not reserved in a DNS name (the "host" field), so
there is no reason that it would be escaped.  If it is internally
un-escaped and the re-escaped the dot might reasonably be left alone. If
viewed as DNS names, the strings "jcifs%2Esamba.org" and "jcifs.samba.org"
mean exactly the same thing.

On the other hand,

  "anonymous:crh%40samba.org at us6.samba.org"
  "anonymous:crh at samba.org@us6.samba.org"

are parsed differently, which changes semantics as well.

When I entered:


I got FTP access to us6.samba.org.  That worked correctly and Netscape
continued to show the %40 in the URL string as I moved up and down in the
directory tree.

  [I have to admit, though, that Netscape also accepted


  which is syntactically incorrect.  Two '@'s should not be allowed in the
  authority field.  A credit to Netscape's parsing and "user

Which browser did you test with?  I have a selection to play with.  It 
would be interesting to see what happens.
