Add URL variables with Server.Transfer in asp.net
<p>I am currently trying to add a variable to the url using Server.Transfer. I need to use Server.Transfer as I need to keep form post data which is why I can't use Response.Redirect.</p>

<p>I am using <code>Server.Transfer("add_account.aspx?error=userNotFound");</code> but the variable is not being added to the URL. </p>

<p>Thanks for your help. </p>
