{
System.Web.HttpContext cxt = context.Context;

if (cxt.Request.ContentType != "image/pjpeg")

string type = cxt.Request.ContentType.ToLower();
string path = cxt.Request.Path;
string apppath = cxt.Request.ApplicationPath;
path = path.Remove(0, apppath.Length);
path = "~" path;

string newUrl = GetUrl(cxt, path.TrimEnd().TrimStart());
if (newUrl != null)
{
cxt.Response.Filter = new ResponseFilter(cxt.Response.Filter, cxt.Request.Path);
cxt.Response.Write("请求的路径:" path);
cxt.Response.Write("");
cxt.Response.Write("转向的目的URL：" newUrl);
cxt.Response.Write("");
cxt.RewritePath(newUrl);
}
//如果要求处理所有的请求时用到
//else
//{
// cxt.Response.Write(cxt.Request.Path "");
// cxt.Response.Write("你请求的资源不存在或无权访问！");
// cxt.Response.Flush();
// cxt.Response.End();
