Support for HTTP forward

[mvcbot]

Original issue MVC_SPEC-23 created by Santiago Pericas-Geertsen:

JAX-RS 2.1 is likely to support a redirect call (just like servlet). This issue is recorded to track if whatever support is added to JAX-RS is sufficient for MVC.

Comment by Santiago Pericas-Geertsen:

Ozark implements redirect using the "redirect:" prefix. For example,

return "redirect:/foo";

which seems very convenient for controller methods returning strings.

Ok.

How do you get to the request.getContextPath() of your application then?

@POST
@Controller
@Path("edit/{id}")
@Produces("text/html")
public Viewable editProduct( @PathParam("id") int id,
                             @FormParam("action") String action,
                             @FormParam("name") String name,
                             @FormParam("description") String description,
                             @FormParam("price") double price )
{
    if ("Save".equalsIgnoreCase(action)) {
       /** ,,,**/
    }
    retrieveAll();
    return new Viewable("redirect:/products.jsp");
}

}

The "redirect:/products.jsp" will alter the URI and still include the Application Path URI e.g.

 http://localhost:8080/acme/gateway/product.jsp

This is probably not what the developer/designer wants. Instead they want

 http://localhost:8080/acme/product.jsp

Assuming the "/acme" is the servlet context path

?

Comment by Santiago Pericas-Geertsen:

The relative path resolution is currently documented to be compatible with javax.ws.rs.core.Response#seeOther, which is also available to MVC controllers that return a Response.

Comment by Manfred Riem:

I think what he is saying what if you want to break out of the servlet path, but instead want to target the context path?

I don't think it is worth to include this in 1.0. Any objections?
