I have one route in my app that must have a text and a dot followed by a format. For example:
http://domain.com/image/mi-text-with-dots-.-in-.-the-.-middle.png
As you can see it’s an url that can contain dots before the dot that splits the {text} and the {_format} parts.
To make this work you have to define the route in routing.yml using a regexp for {text} this way:
dotted_url:
pattern: /image/{text}.{_format}
defaults: { _controller: AcmeDemoBundle:Demo:image, _format: png }
requirements:
_format: png|jpg
text: .+
