I you have a change URL like:
http://localhost:8080/c/test-project/+/688
Stepping back to parts "../../" will get you:
http://localhost:8080/c/
Wich is _not_ the base url.
Do not try to guess how URL is constructed but trust WebLink providers
to provide an absolute or a relative URL.
Provide correct relative url from Gitweb.
