Re: [Cppcms-users] url dispatching

[Vinicius P. <ds...@ha...>]

It's regular expressions.

When you say "/number/(\\d+)" you mean to check for strings starting
with /number/ and capture all numbers following it "(\\d+)", the 1 after
is to pass this parameter.

When you say ".*" it means every strings, as "." match every char and *
means any number of it, the 0 means it will not pass arguments as it
don't capture nothing.

If you are still lost, look for a tutorial on regexp or regular
expression on the net.

The pointer is the &hello::number part, a pointer to a function, and you
must pass this as it's a function of a class.

Hope this helps,
Vinicius
