Symfony2 – Franz Jordán 2011
Summary
Routing is a system for mapping the URL of incoming requests to the controller function that
should be called to process the request. It both allows you to specify beautiful URLs and keeps
the functionality of your application decoupled from those URLs. Routing is a two-way
mechanism, meaning that it should also be used to generate URLs.

How to force routes to always use
HTTPS
Sometimes, you want to secure some routes and be sure that they are always accessed via the
HTTPS protocol. The Routing component allows you to enforce the HTTP scheme via
the _schemerequirement:
secure:
pattern: /secure
defaults: { _controller: AcmeDemoBundle:Main:secure }
requirements:
_scheme: https
The above configuration forces the secure route to always use HTTPS.
When generating the secure URL, and if the current scheme is HTTP, Symfony will automatically
generate an absolute URL with HTTPS as the scheme:
# If the current scheme is HTTPS
{{ path('secure') }}
# generates /secure
# If the current scheme is HTTP
{{ path('secure') }}
# generates https://example.com/secure
The requirement is also enforced for incoming requests. If you try to access the /secure path
with HTTP, you will automatically be redirected to the same URL, but with the HTTPS scheme.
The above example uses https for the _scheme, but you can also force a URL to always
use http.
The Security component provides another way to enforce the HTTP scheme via
therequires_channel setting. This alternative method is better suited to secure an "area" of
your website (all URLs under /admin) or when you want to secure URLs defined in a third party
bundle.
