Symfony 1.4 require a domain name in routing

Question

I need to require a domain name in my symfony routing, my route looks like the following:

domain_example:
url: /routing/example/:domain_name
param: { module: myModule, action: index, sf_format: json }
requirements: { domain_name: '/^[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}$/' }

I have also tried:

requirements: { domain_name: '[/^[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}$/]' }

If I call my route like so: mydomain.com/routing/example/otherdomain.com - I just get the module/action does not exist exception.

To summarize

dot are used as segment separator in Symfony. So you should add this option to your route to force Symfony to only use / as separator:

  options:
    segment_separators: [/]

Next, your regex is wrong, but SO has one for you:

[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(:[0-9]{1,5})?(\/.*)?

Your final route:

domain_example:
  url: /routing/example/:domain_name
  param:
    module: main
    action: index
    sf_format: json
  requirements:
    domain_name: '[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(:[0-9]{1,5})?(\/.*)?'
  options:
    segment_separators: [/]
