[Cppcms-users] Mounting both synchronous and asynchronous applications

[CN <cn...@gr...>]

Hello,

Imagine my site has both synchronous (for user login) and asynchronous  
(for interactive activities) pages. Is it a correct and good practice to  
mount both synchronous and asynchronous applications like the following  
code?

//code begin
class login:public cppcms::application{ .... }
class interaction:public cppcms::application{ .... }

int main()
{
cppcms::service s(argc,argv);

s.applications_pool().mount(cppcms::applications_factory<login>());

booster::intrusive_ptr<interaction> i=new interaction(s);
s.applications_pool().mount(i);

s.run();
}
//code end

Please also correct me if my following thoughts are wrong:

- When a request arrives, cppcms::service.run() loops all mounted  
applications and pass that request to every mounted application. It is the  
responsibility of every application to filter the interested passed in  
request by applying dispatcher().assign().

- This program can fire multiple instances of "login" class. Every login  
instance runs as a separate thread. Thus this program can concurrently  
process multiple incoming synchronous (login) requests.

- This program process asynchronous requests only one at a time because  
only one instance of class "interaction" is created. As such, asynchronous  
applications are most likely the bottleneck of performance when the load  
is heavier.

Thank you in advance!
