Symfony Match Route with Multiple Hosts - symfony

Question

I know it is possible to filter a route by host, like this:
irc_backend.report.stacking_issue:
path: /reports/stacking-issues
host: backend.domain.com
defaults: { _controller: IRCBackendBundle:Reports/Product/StackingIssueReport:index }
Is it possible to alter this configuration to match multiple domains? For example:
irc_backend.report.stacking_issue:
path: /reports/stacking-issues
host: backend.domain.com|dev.backend.domain.com
defaults: { _controller: IRCBackendBundle:Reports/Product/StackingIssueReport:index }
I'm trying to avoid setting up 2 routes for every page.

Answer 1

You can try placeholders in your hostname with requirements (i.e.. Symfony Documentation)
irc_backend.report.stacking_issue:
path: /reports/stacking-issues
host: "{mydomaines}"
defaults: { _controller: IRCBackendBundle:Reports/Product/StackingIssueReport:index }
requirements:
mydomaines: backend.domain.com|dev.backend.domain.com

Answer 2

If you read the Symfony documentation, you'd know that you need to use placeholders. For your code, it would be :
irc_backend.report.stacking_issue:
path: /reports/stacking-issues
host: "{subdomain}.domain.com"
defaults:
_controller: IRCBackendBundle:Reports/Product/StackingIssueReport:index
subdomain: backend
requirements:
subdomain: backend|dev.backend
I hope it'll help you !
EDIT :
If you want your default subdomain to be the current one, you can use a parameter like this :
irc_backend.report.stacking_issue:
path: /reports/stacking-issues
host: "{subdomain}.domain.com"
defaults:
_controller: IRCBackendBundle:Reports/Product/StackingIssueReport:index
subdomain: "%subdomain%"
requirements:
subdomain: backend|dev.backend
Then you will be able to define this parameter in an Event listener with this line of code :
$container->setParameter("subdomain", $your_subdomain);
P-S : Don't forget to add the Service container to your listener's dependencies
