feat(routeProvider): Add support to catch-all parameters in routes
Browse files Browse the repository at this point in the history
This allows routeProvider to accept parameters that matches
substrings even when they contain slashes if they are prefixed
with an asterisk instead of a colon.
For example, routes like edit/color/:color/largecode/*largecode
will match with something like this
http://appdomain.com/edit/color/brown/largecode/code/with/slashs.
