Question

I want to create a network like stackexchange just with subdomains.

for example

subdomain1.test.com
subdomain2.test.com
subdomain3.test.com
subdomain4.test.com

I also want to have all websites in one app so I can scale and service them easier.

How do I do this in play2?

Can i specify a subdomain in routes?

pseudo code

GET     subdomain1/                           controllers.Application.index()
GET     subdomain2/                           controllers.Application.index()

Answer 1

It will not work: if router contains two routes with the same type and target action it will use only first. For fastest solution you can just create a wrapping method(s), which will do what you need and use them on the view/controller level:

route

GET   /home    controllers.Application.index

Application controller

public static String linkMeta(play.api.mvc.Call path) {
    return "http://meta.domain.tld" + path;
}

Template samples:

<a href='@Application.linkMeta(routes.Application.index)'>Absoulte URL link to meta's index</a>
URL: http://meta.domain.tld/home

<a href='@routes.Application.index'>Relative URL to meta's index</a>
URL: /home
