I think this is wrong.
From the URI RFC: "A path consists of a sequence of path segments separated by a
slash ("/") character."
Here you are decoding "%2f" into "/" *before* deciding on where to split the
path segments. I think you do need to find the path-segments first, and then
decode each.

Done.
