Propagating request parameters from root context

Hi,

I want to know if it is possible to propagate request parameters from the root context url path?

Normally it is possible to propagate the request parameters using param in page.xml:

<param name="parameter_name"/>

So if it's made request:

http://domain/root_context/home.seam?parameter_name=something

and there is not current session the user is redirected to:

http://domain/root_context/login.seam?parameter_name=something

In my case I need to propagate the request parameter from the root context path:

http://domain/root_context/?parameter_name=something

That´s because I'm developing Facebook Canvas app.

I guess that I'm loosing the propagation because of the use of index.html in welcome list with source:

<html><head><meta http-equiv="Refresh" content="0; URL=home.seam"/></head></html>

There is a way to accomplish propagation of the request parameter from context root path?

Hi Ico!
You can do that with index.jsp instead of html. In the jsp put a scriptlet where you read the request parameter and if presented, attach it to the redirecting page

<% String param = request.getParameter("param_name"); String url = "home.seam"; if (param!=null) { url = url + "?param_name=" + param; } response.sendRedirect(url); %>
