symfony - what is the difference between MASTER / SUB REQUEST in Symfony2?

Question

so im reading the internals documentation for symfony2 http://symfony.com/doc/current/book/internals.html and i dont understand this section http://symfony.com/doc/current/book/internals.html#events.

so, i want to know the difference between MASTER / SUB REQUEST ?

Answer 1

The master request is the one that comes from the original user; the subrequest is the one that you do internally — either with the forward() method of HttpKernel — or by the forward() helper of the framework's Controller class — or {% render ... %} in Twig.
