How to make a link that takes you back from https to http?

Question

I have this link on my page (page1):

<a href="@{Controller.action1().secure()}">Link1</a> 

that takes me to a page (page2) over https. How to make a link on page2 that takes me back from https to http? I thought @@ notation would do the trick:

<a href="@@{Controller.action2()}">Link2</a>

but it doesn't, action2 also gets called via https.

Play doesn't have a method that would be opposite to secure(), but you can implement it yourself with custom JavaExtension:

import play.templates.JavaExtensions;
import play.mvc.Router.ActionDefinition;

public class MyExtensions extends play.templates.JavaExtensions {

    public static String unsecure(ActionDefinition action) {
            if (!action.url.contains("http://") && !action.url.contains("https://")) {
                action.absolute();
            }
            action.url = action.url.replace("https:", "http:");
            return action.url;
        } 

Custom extension methods should return String, and the parameter will hold the enhanced object, as the documentation suggests. The code is almost identical to the secure method's code.

With this method you can now use:

href="@{Controller.action2().unsecure()}"
