Re: [Cppcms-users] Heavy background processing

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

Yeah I've seen that.

Here is what I'd need to do:

Async app sends a handler to threadpool to execute a heavy processing
task via threadpool::post. Ok

Suppose the heavy processing task wants to print out a status ie. "Task
1 processed, Task 2 processed etc" and want to send it back the the
Async app that move the processing to the thread pool so that they can
be displayed on a webpage via a long-polling request.

Is service::post() used for this?

If there was multiple async apps, how to designate the one that should
receive these messages?

What am I missing?
