修改user/checkuserlogin.asp文件,加下面红色的吧

if GCls.ComeUrl<>"" then
          ToUrl=GCls.ComeUrl
          GCls.ComeUrl=""
          response.write "<script>top.location.href='" & ToUrl & "';</script>"
         Else
          response.write "<script>window.open('index.asp');location.href='" & ToUrl & "';</script>"
         End If
