Httpmodule代码:
public class Error404Module : IHttpModule
{
public void Init(HttpApplication context)
{
context.Error += new EventHandler(Context_Error);
}
protected void Context_Error(object sender, EventArgs e)
{
HttpContext ctx = HttpContext.Current;
HttpResponse response = ctx.Response;
HttpRequest request = ctx.Request;
Exception ex = ctx.Server.GetLastError();
HttpException hex = ex as HttpException;
if (hex != null && hex.GetHttpCode() == 404)
{
ctx.Server.ClearError();
string url = request.Url.AbsoluteUri.ToLower();
if (url.Contains(@"http://hj.woniu.com"))
{
url = url.Replace(@"http://hj.woniu.com", @"http://sg.hj.woniu.com");
}
response.Redirect(url, true);
}
}
public void Dispose()
{
}
}
