Ciao, ti ringrazio, ho sistemato con le tue info.

var regex1 = new Regex("^/offerte-last-minute-(.*)", RegexOptions.IgnoreCase);
var match1 = regex1.Match(Request.Url.AbsolutePath);
if (match1.Success)
HttpContext.Current.RewritePath("/index.asp?zona=" + match1.Groups[1].Value);

ecc ecc

Gabriele
