I am trying a simple example with CppCms and I would like to execute all my applications relative to the web application root. I don't want execute the application relative to the script path. Ex localhost: 8080/script-path/relative-path-to-my-application, and instead of this, I would like the path for my application would be like: localhost: 8080/relative-path-to-my-application. I would like to execute this application using the CppCMS-Embedded. I am trying a super simple example and I had no success. All the time I try the root url (http://localhost:8080/) I get a 404 error like that:

Below the code and config files that I made:

#include <cppcms/application.h>
#include <cppcms/applications_pool.h>
#include <cppcms/service.h>
#include <cppcms/http_response.h>
#include <cppcms/url_dispatcher.h>

class my_app : public cppcms::application{
public:
my_app(cppcms::service& s) : cppcms::application(s){
dispatcher().assign("",&my_app::well_come,this);
mapper().assign("");
mapper().root("");
}
void well_come(){
content::index ci;
ci.message = "Hello ";
render("index",ci);
}
};
int main(int argc,char ** argv){
try{
cppcms::service srv(argc,argv);
srv.applications_pool().mount(
cppcms::applications_factory<my_app>()
);
srv.run();
}catch(std::exception const & e){
std::cerr<<e.what()<<std::endl;
}
}
config.js:

What's I missing in my configurations? Why the CppCMS-Embedded is not routing for the web application root . Thanks.
After some threads in the CppCms community, Artyom Beilis opened my mind for this issue. All the time that I requested the root url like that http://domain.com/, I got a 404 error due to that the CppCms always expects at least some mapping that is not empty, like "/" or any other string that start with "/" . The correct way is always to map to something that start with "/". A good solution proposed by Artyom Beilis is to keep the url's rewrite in the same form like the tutorial: How to run the application at the root of the web server. And add a mapping that is not empty that matches with the default url, like that:
dispatcher().assign("/",&my_app::well_come,this);
mapper().assign("well_come","/");
This solution works pretty well for me =;)
