Redirect or forward in web application

Hi All

I have a requirement like, from some web page on some event user will redirect to MyApp's login page with some parameter. I want to test MyApp is able to get that parameter or not. To test that i made another app in which i am using (code is below ). But this is showing parameter in url which i don't want. I also want to know what other ways are there to redirect/forward to some another url with parameter开发者_开发技巧 ( parameter should be hidden hiddn ).

<% response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY); response.setHeader("Location","http://localhost:8080/MyApp/login/login.jsf?user_id=inc&reference_id=123456789"); %>

It's not possible to do POST redirects, so you can't just redirect with a POST from your scriptlet.

What you can do is:

• Build an HTML form in POST with the parameters that you want to pass, but remember, the POST perceived security is brittle, since with a tool like firebug anyone can see those variables (or they can just look at the html source).

• A way around the problem is use encryption or one time passwords (that last for a session). I used this way, to connect seamlessly a Java application with PHP. If you're interested I could look it up and share the details of that solution.

First of all, do not use scriptlets. If you dont want to see the parameter in the URL, don't send it with the URL. You can do a POST submit or pass it as a hidden variable from your page.
