Support for flexible routes

[avaly]

Disclaimer: this is a duplicate post for hapijs/hapi#2058

According to http://hapijs.com/api#path-parameters and the actual implementation of routes in v7+, one can not register the following route: /{foo}-custom-string-{bar}, due to the restriction that a path segment can not contain more than one parameter.

This should be changed and it should allow the creation of more flexible routes. Not all users of hapi use it to create only API sites, some of us use it to run a user facing site where SEO and the public URL structure is important.

I know we can do this by using a single parameter for the whole segment and then parsing that parameter inside the handler method, but that ruins the whole idea of using a framework that handles these small things for you.

I don't if the hapi team wants to go in that direction, and is there are other frameworks supporting this ? (Just curious, this is the first time I see this). I could work on this and propose a PR, if needed.

This can be achieved with express via their router.param method or even by defining a route using regular expression (which gives the best flexibility).

Having some similar features would help expand the reach of the hapi framework.

Okay, I didn't know about it. Thanks ^^ But how will you handle the case ```/{foo*2}-custom-string-{bar} ? I don't know for the moment if this will break a lot of logic.

Well, I guess you shouldn't be allowed to use /{foo*2}-custom-string-{bar}, but only allow using multiple single parameters within the same segment.
