Don't remove the parameters.

There is no reason for that, relative paths resolve correctly with the 
parameters included.  (In fact they would resolve incorrectly when you 
remove the parameters.)


Example base URL:
http://localhost/dir;im_ignoring=this/subdir;and=this/index.html

And some relative URL examples expanded:

#top -> http://localhost/dir;im_ignoring=this/subdir;and=this/index.html#top

page.html -> http://localhost/dir;im_ignoring=this/subdir;and=this/page.html

../index.html -> http://localhost/dir;im_ignoring=this/index.html

../subdir;and=that/index.html -> http://localhost/dir;im_ignoring=this/subdir;and=that/index.html

/index.html -> http://localhost/index.html

/anotherdir;param=value/index.html -> http://localhost/anotherdir;param=value/index.html
