是否有可能使用ASP.NET会话时，强制要求并发？ [英] Is it possible to force request concurrency when using ASP.NET sessions?
问题描述
ASP.NET不允许在同一会话并发请求;这意味着用户只能做一次1请求。
ASP.NET does not allow concurrent requests for the same session; meaning that a user can only make 1 request at a time.
举例来说，假设我们有 Test1.aspx ：
For example, say we have Test1.aspx:
public partial class Test1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Session["test"] = 1;
System.Threading.Thread.Sleep(int.Parse(Request.QueryString["timeout"]));
}
}
...和 Test2.aspx ：
public partial class Test2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Session["test"] = 1;
Label1.Text = DateTime.Now.ToString("dd/MM/yy HH:mm:ss");
}
}
当我们访问 Test1.aspx？超时= 10000 ，然后访问后，立即 Page2.aspx 中，第二个请求将不得不等待10秒钟，直至第一个请求已完成。
When we visit Test1.aspx?timeout=10000, and then immediately after visit Page2.aspx, the 2nd request will have to wait for 10 seconds until the first request has finished.
我今天这个刚刚学会的，我一直在使用ASP.NET 5年！我真的不相信它，直到我在一个MSDN页面的底部（的 ASP.NET会话状态概述）。
I just learnt this today, and I've been using ASP.NET for 5 years! I didn't really believe it until I read it at the bottom of an MSDN page (ASP.NET Session State Overview).
那么，有没有办法迫使并发？也就是说，不是使网页的速度更快，或移动长期运行code到后台线程等。我知道，你可以只读会话，但我不能完全肯定这是一个可行的选择。
So, is there a way to force concurrency? That is, other than making pages faster, or moving long running code to a background thread. I'm aware that you can make the session read only, but I'm not entirely sure this is a practical option.
推荐答案
虽然我刚刚得知这个距离的问题，我会确保检查锁定会话存储数据一节中的实现会话状态存储提供商，关于更多信息，为什么它完成。
Although I just learned this from the question, I'd make sure to check the Locking Session-Store Data section in Implementing a Session-State Store Provider, for more information on the why its done.
根据上述情况，它确实似乎并不像一个好主意，尝试解决这一机制。
Based on the above, it really doesn't seem like a good idea to try to work around that mechanism.
像你所说，保持请求短，移动长期运行code OUT请求的线程。另外：
Like you mentioned, keep the requests short and move long running code out of the request thread. Additionally:
- 关闭会话，如果你不需要它。更重要的是这样做的，如果你发送任何在该请求大。
- 避免会议的不必要使用。
所有这些都是一些你应该已经做反正
All of those are something you should already be doing anyway.
