How to POST the data from one page to another page without QueryString?

 

Aim :
       
            How to send secure data (like UserID , Password , Encrypt Key, & etc) from one page to another page.

Possible Ways are:

•    1.  Query String [ security issues - User can read the data].
•    2.  Cookies
•    3.  Session [ It's Support only within site]
•      etc......

Now we can see How to send the data from one Site page to another site page without  QueryString.

Steps

• First we create two Web application (1. Data sender , 2. Data Receiver ) 
• Design Two Pages like bellow .

 Data Sender

• Set the Submit button Property "PostBackURL"

• There is no need to write any code in sender page

Data Receiver

• Design the page like this

• Page load Code Block

   protected void Page_Load(object sender, EventArgs e)
  {
          lblUserName.Text = Request.Params["txtUserName"];
          lblPassword.Text = Request.Params["txtPassword"];
          lblKey.Text = Request.Params["txtKey"];
  }

• Now run the both applications.

• Fill the data in Sender page & click the submit button.
• Once we click the submit button, we can see the second site page, with fist site page data.
