Working in ASP.NET 2.0 VB, I need to check for the existence of a cookie on entering a page and if it exists, immediately redirect to another page. This is a validation portal and further down on the page, I am also checking for the value of the cookie (in the page behind code) to see if it has been set, and if not, then setting it(this part is working). In other words, the first time a user hits this page, he has has to check a box before being directed to his destination page. On subsequent visits during the same browser session, the user is sent directly to the destination page.
How can I check for this cookie without loading the page? Do I put a script in the <head> of the page? And what would the code look like. I need some guidance here. Thanks.
protected void Page_Load(object sender, EventArgs e)
{
if (this.Request.Cookies["cookiename"] != null && this.Request.Cookies["cookiename"].Value == "Expectedvalue")
{
this.Response.Redirect("URL TO REDIREC TO");
}
}

Now to check it on the live server....
Now the next question is how do I integrate the development web.config file with the live one. I think I had better start a new thread. Thanks to all who helped.
