How to create the route in symfony 2 which maps to external URL?
Referring to this,
http://symfony.com/doc/current/book/routing.html
we can map url pattern to controller and action
app/config/routing.yml
blog_show:
path: /blog/{slug}
defaults: { _controller: AcmeBlogBundle:Blog:show }
I want to map the path to external url.
app/config/routing.yml
blog_show:
path: /blog/{slug}
defaults: "www.example.com/blog"
The requirement is, my current website is in kohana, I am porting it gradually to symfony 2. For my symfony2 app kohana URL are like external urls, I want to configure these urls in routing and use them in standard way,
eg in Twig,
<a href="{{ path('blog_show'}}">
Read this blog post.
</a>
So later on when I port my pages to Symfony, I will have to change only routing file so that I could use same blog_show key to refer to url and I wont' have to change all the files where I have used urls.
You can do this by using one of the Symfony framework controllers although I'm not sure how this would work with parameters:
blog_show:
path: /blog/{slug}
defaults:
_controller: FrameworkBundle:Redirect:urlRedirect
path: "http://example.com/blog"
permanent: true
Note that path: /blog/{slug} grabs the slug directly, but path: "http://example.com/blog/{slug}" doesn't work.

As of Symfony 2.2 this is possible by adding the host constraint to the routes:
routing.yml
user_homepage:
path: /path/to/whatever
host: "sub.domain.ext"
defaults:
_controller: forExampleAnyNamespaceBundle:Controller:action
There's an official blog post on this issue: http://symfony.com/blog/new-in-symfony-2-2-url-host-support-in-the-routing
The router feature of Symfony doesn't work that way...
I suggest you create a Twig extension for this. Read more about this here: http://symfony.com/doc/current/cookbook/templating/twig_extension.html
You could create a function that works very similar to the regular url() function, so you can migrate as easily as possible.
{{ legacyUrl('blog_post', {slug: 'my-blog-post'}) }}
After you migrated the blog to Symfony, all you need to do is create a route called "blog_post" and change "legacyUrl" to "url".
