I'm using webrick (the built-in ruby webserver) to serve .rhtml files (html with ruby code embedded --like jsp).
It works fine, but I can't figure out how to access parameters (e.g. http://localhost/mypage.rhtml?foo=bar) from within the ruby code in the .rhtml file. (Note that I'm not using the rails framework, only webrick + .rhtml files)
Thanks

According to the source code of erbhandler it runs the rhtml files this way:
Module.new.module_eval{
meta_vars = servlet_request.meta_vars
query = servlet_request.query
erb.result(binding)
}
So the binding should contain a query (which contains a hash of the query string) and a meta_vars variable (which contains a hash of the environment, like SERVER_NAME) that you can access inside the rhtml files (and the servlet_request and servlet_response might be available too, but I'm not sure about them).
If that is not the case you can also try querying the CGI parameter ENV["QUERY_STRING"] and parse it, but this should only be as a last resort (and it might only work with CGI files).

This is the solution:
(suppose the request is http://your.server.com/mypage.rhtml?foo=bar)
<html>
<body>
This is my page (mypage.rhtml, served by webrick)
<%
# embedded ruby code
servlet_request.query ["foo"] # this simply prints bar on console
%>
</body>
</html>
