Re: [Cppcms-users] URL dispatching help

[<ele...@ex...>]

it's simple

dispatcher = URL to function
mapper = key to URL

look at the url_mapper::assign function and read the url_mapper class doc
entirely.

http://cppcms.com/cppcms_ref/1.0.0/classcppcms_1_1url__mapper.html

you designate a "key" to a particular page, and when you call that "key"
within your code, it's translated to an URL.

Say you name a key "edit", and map it to /edit/{1}.
