I think I got your point: All in all this is still a matter of comparing the first against the current url and counting the common dirs from the left side. Then you compare that number(a) to the depth of the first url(b) and add b-a "../" so you get to the right position inside your base.
By that way if you call "wget -r --base=/somedir /server/otherdir/" a later reference to /server/otherdir/ is correctly found as duplicate of the first one. I first thought of a different solution... like appending initial-depth-times ".." to base. I admit this is silly. Now i think this could result in different problems like what schould happen with "wget -r --base=/home/matthias/tmp http://server/with/a/complicated/structure/and/to/many/dirs/a.php"; If you now have a link to "/index.html" you would try to access some file above / or am I wrong?
