# javascript's RegExp::exec method won't find anything even when the
# regex matches!
#
# It's also imporant we return a fresh copy of the RegExp every time. A
# javascript regex is stateful and multiple functions using this method
# will cause unexpected behavior!

# This tests for valid schemes as per RFC 3986
# We need both http: https: and mailto: and a variety of other schemes.
# This does not check for invalid usage of the http: scheme. For
# example, http:bad.com would pass. We do not check for
# protocol-relative uri's.
