ASP到ASP.NET会话变量

Question

我们有一个经典asp的网站,我们正在慢慢迁移到ASP.NET.

问题当然是经典的asp和ASP.NET如何处理Sessions.在花了最后几个小时研究网络之后,我发现了许多文章,但没有一篇文章比其他文章更突出.

是否有最佳实践将会话变量传递给经典的asp和asp.net？安全是必须的,并且非常感谢任何带有示例的解释.

将经典asp中的单个会话变量传递给.net服务器端(从客户端隐藏会话值)的简单桥接器将是:

• 在ASP端:输出会话的asp页面,称之为asp2netbridge.asp

  <%
  'Make sure it can be only called from local server '
  if (request.servervariables("LOCAL_ADDR") = request.servervariables("REMOTE_ADDR")) then
      if (Request.QueryString("sessVar") <> "") then
          response.write Session(Request.QueryString("sessVar"))
      end if
  end if
  %>
  

• 在.net端,远程调用该asp页面.:

  private static string GetAspSession(string sessionValue)
   {
      HttpWebRequest _myRequest = (HttpWebRequest)WebRequest.Create(new Uri("http://yourdomain.com/asp2netbridge.asp?sessVar=" + sessionValue));
      _myRequest.ContentType = "text/html";
      _myRequest.Credentials = CredentialCache.DefaultCredentials;
      if (_myRequest.CookieContainer == null)
          _myRequest.CookieContainer = new CookieContainer();
      foreach (string cookieKey in HttpContext.Current.Request.Cookies.Keys)
      {
          ' it is absolutely necessary to pass the ASPSESSIONID cookie or you will start a new session ! '
          if (cookieKey.StartsWith("ASPSESSIONID")) {
              HttpCookie cookie = HttpContext.Current.Request.Cookies[cookieKey.ToString()];
              _myRequest.CookieContainer.Add(new Cookie(cookie.Name, cookie.Value, cookie.Path, string.IsNullOrEmpty(cookie.Domain)
                  ? HttpContext.Current.Request.Url.Host
                  : cookie.Domain));
          }
      }
      try
      {
          HttpWebResponse _myWebResponse = (HttpWebResponse)_myRequest.GetResponse();
  
          StreamReader sr = new StreamReader(_myWebResponse.GetResponseStream());
          return sr.ReadToEnd();
      }
      catch (WebException we)
      {
          return we.Message;
      }
  }
