Why doesn't xdebug in phpstorm suspend session when switching from frontend to backend?

Question

xdebug

I have a virtual machine: ubuntu-server+apache+xdebug
When I start the debugging process in phpstorm and the functions on the backend are called, the session does not seem to be suspended, and if I do not have time to complete the work of the functions on the backend, then something like this:

Error Fetching http headers

Google says you can increase the default_socket_timeout in php.ini on the server. But this is not quite what we would like.
How could I pause the current session and continue it when I continue the script manually?

For nginx, it's done like this:

For Apache, understand by analogy. And think about the fact that in 2016 you should not use such old technologies.
