[Cppcms-users] What exactly url_mapper does?

[Abhishek K. <abh...@gm...>]

Hi, 

I have been going with the examples and documentations.

I fully understand the functionlity of url_dispatcher, like how it links to
applications functions filtering it from regex and passing the filtered value as
parameters (I am referring the dispatcher.assign() function here).

I am still not able to make any clue about url_mapper (mapper.assign()
actually). I have been seeing it to be used in with dispatcher function, is it
mandatory?
does the mapper function as to be used along with dispatcher?

Can you explain in the very simplest term & example, what exactly url_mapper
does? and how can it be similar and different from dispatcher?

Thanks
