How do I make a client side http request in opa?

Question

I need to make a client side http request to receive a string. I am struggling to find a method that works on the client.

I found WebClient.Get. But this one only works on the server. Threading it through opa's client/server communication is not an option because I need this to work, even if the server is down.

Browsers do not allow cross domain requests for security reason. See http://en.wikipedia.org/wiki/Same_origin_policy

Something is planned in HTML5 to overcome this (and beta versions of Chrome have net client support), but currently you need to use server-side functions. Hopefully, it's easy to do with Opa.

Actually that is possible with jsonp and jquery has support for this. Also, my http request would be same domain. Its not a question of protocol/policy but rather, and in a broader sense: How to execute custom javascript on the client via opa? That is a different question but its answer would provide me with a workaround. – Martin Lütke Jul 04 '12 at 10:22
To force the execution of code on the client side, use "client" directive (http://doc.opalang.org/manual/Developing-for-the-web/Client-server-distribution). – Cédrics Jul 05 '12 at 10:20
To use existing js, create a plugin ( http://blog.opalang.org/2012/01/reusing-javascript-libraries-jquery-ui.html) – Cédrics Jul 05 '12 at 10:23
