Posting data from one asp.net page to another

Question

Ok I have done enough research on it but cant find the solution. Its from one page of a application to another page of application. Since I would be sending in username and password i cant send it as "getT" so i need to do a "post". I will be using ssl though - not sure if that helps.. so i cant use sessions as its on different apps and using those shared sessions like databsae is performance killing Also once the user clicks the link on the source page, i need to do some post processing and then want to post to the other page so using the form and stuff wont work..

any help

fyi: What I am trying to achieve is that a person when logs in app A, they click some link, i dont some processing and want to transfer them to app B where they dont have to relogin in app B but instead automatically get logged in..

Answer 1

Maybe not the best solution, but you could use a cookie.

Answer 2

We use Global.asax to do much the same thing you are describing. Assuming both web apps use the same business domain. You can use the following to set a logged in user in our business domain. You can then use the presence of that property to know not to ask for login again on your second Web App.

    /// <summary>
    ///     Event fires when an HTTP request is made to the application.
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void Application_PreRequestHandlerExecute(object sender, EventArgs e)
    {
        // If we don't have a logged in user.
        if (<BusinessDomain>.Constants.LoggedInUserID == null)
        {
            // Ensure that Context.Handler for this particular HTTP request implements an interface that uses a Session State.
            if (Context.Handler is IRequiresSessionState || Context.Handler is IReadOnlySessionState)
            {
                if (Session != null)
                {
                    // Set the currently logged in user in our Business Domain.
                    if ((Guid)Session["UserID"] != Guid.Empty)
                    {
                        <BusinessDomain>.Constants.LoggedInUserID = Session["UserID"];
                    }
                }
            }
        }
    }

Answer 3

I think you're looking for a Single Site Login solution.

Answer 4

Agree with Thomas, sounds tailor made for the single sign on solution. Multiple web apps using a single sign on, so once you log in on one app you logged in on all that reference the membership provider..
