redirect back to referrer

[Hellp]

Any help appreciated.

Have users on the local area net work post to an Aspx page. The page
process some post data.

I would like to return the user's browser back to the sumbit page. I
have tried

hplReturn.NavigateUrl = Request.UrlReferrer.ToString

but get the following error:

"Object reference not set to an instance of an object"

Any help appreciated

the first page opened doesnt have a referrer, so check if
request.UrlReferrer is nothing first. like:

if not request.UrlReferrer is nothing then
response.redirect (request.UrlReferrer.tostring)
end if

what if they directly typed the url or used the link from favourites...
there wont be no referrer.
so check for
first things first
if(!Page.IsPostback)
{
ViewState["URLReferrer"] = Request.UrlReferrer;
}

when you want to direct
if(ViewState["URLReferrer"] != null)
{
Response.Redirect(Convert.ToString(ViewState["URLReferrer"]))'
}
else
{
Response.Redirect("~");
// ~ redirect to current application's default page
}
