How do I safely join relative url segments?

Question

I\'m trying to find a robust method of joining partial url path segments together. Is there a quick way to do this?

I tried the following:

puts URI::

The problem is that resource/ is relative to the current directory, but /edit refers to the top level directory due to the leading slash. It's impossible to join the two directories without already knowing for certain that edit contains resource.

If you're looking for purely string operations, simply remove the leading or trailing slashes from all parts, then join them with / as the glue.
