#7 CommonUtils.fullUrl: ".." is not handled correctly

[fuero]

I ran into a problem with an IIS (I tested the same with an apache server, worked fine) server today, encountering links that looked like that:

foobar

Passing this url through sys.fullUrl(), I got this:

http://www.example.com/foo/../bar.htm.

Apparantly, this server doesn't like this url, it closes the connection. Sending the request with a web browser or other tools doesn't trigger this problem, as they seem to procees this url. I confirmed that with wireshark.

I'm uploading a fix too, which works for me.

Resolves '..' in links
