I have this line of code: Response.Redirect(HttpContext.Current.Request.ApplicationPath & "/ClaimantList.aspx?Submit=Search&ClaimantSearch=" & tbSearch.Value.ToString) It works fine on my localhost, but when I upload it to a webserver and hit it, it attempts to redirect to something like: http://claimantlist.aspx/?Submit=Search&ClaimantSearch=pa Why is it munging the URL like that? It's hard to debug when it doesn't happen in debug mode. grrrr...
