Question: I am redirecting to a page changepassword, I want to pass the useremail and password in the url which I get in the current page. How can I pass it in the url. I dont want to use session or cookie. 

```
 Response.Redirect("ChangePassword.aspx");

```

Answer: 
Please use **Session** object to keep this information!!!

Have a look [ASP.NET Session State Overview](http://msdn.microsoft.com/en-us/library/ms178581.aspx) 

Don't use 

```
Response.Redirect("ChangePassword.aspx?password=_543k@sdfPASS");

```

to send any security data!!!
`Response.Redirect("ChangePassword.aspx?username=user&password=pass");` same as Querystring passed from Ajax.

but that's not a good idea
