异步从ASP.NET发出10个POST请求 [英] Making 10 POST requests from ASP.NET asynchronously
问题描述
大家好，
是否可以异步从ASP.NET发出10个POST请求？我已经花了几天时间来解决这个问题，而且我似乎还在继续运行
来应对IIS限制。基本上这里是现在正在运行的过程
（同步）：
人员访问mywebsite.com并填写表格
mywebsite.com向providerwebsite.com发送一个请求
mywebsite.com收到回复
mywebsite.com向providerwebsite.com发送第二个请求
mywebsite.com收到回复
....
mywebsite.com向providerwebsite.com发送第10个请求
mywebsite.com收到回复
我想要发生的事情（异步）：
访问mywebsite.com并填写表格
mywebsite.com向providerwebsite.com发送一个请求
mywebsite.com向providerwebsite.com发送第二个请求
mywebsite.com收到第一个响应请求
....
mywebsite.com向providerwebsite.com发送第十个请求
mywebsite.com收到对第九个请求的响应
mywebsite.c om收到对第十个请求的回复
上面只是一个例子 - 响应应该能够以异步方式到达任何
顺序。问题是，每个请求最多可能需要800个b / b $ b ms才能响应，10次同步请求时间= 8秒......太长了...
这个想法是如果我可以异步发送所有十个请求，结果
应该开始更快地返回。
这是否可以用于ASP.NET和IIS？
Hi all,
Is it possible to make 10 POST requests from ASP.NET asynchronously? I have
been working on this problem for a few days now, and I seem to keep running
up against IIS limitations. Basically here''s the process as it works now
(synchronously):
Person visits mywebsite.com and fills out a form
mywebsite.com POSTs one request to providerwebsite.com
mywebsite.com receives response
mywebsite.com POSTs a second request to providerwebsite.com
mywebsite.com receives response
....
mywebsite.com POSTs a tenth request to providerwebsite.com
mywebsite.com receives response
What I would like to happen is (asynchronously):
Person visits mywebsite.com and fills out a form
mywebsite.com POSTs one request to providerwebsite.com
mywebsite.com POSTs a second request to providerwebsite.com
mywebsite.com receives a response to first request
....
mywebsite.com POSTs a tenth request to providerwebsite.com
mywebsite.com receives a response to ninth request
mywebsite.com receives a response to tenth request
The above is just an example - the responses should be able to arrive in any
order asynchronously. The problem is that each request can take up to 800
ms to respond, times 10 synchronous requests = 8 seconds... way too long...
The idea is that if I can send all ten requests asynchronously, the results
should start being returned much faster.
Is this even possible with ASP.NET and IIS?

大家好，
是否有可能异步地从ASP.NET发出10个POST请求？我现在已经在这个问题上工作了几天，而且我似乎一直在努力克服IIS的限制。基本上就是这个过程，因为它现在（同步）工作
：
人访问mywebsite.com并填写表格
mywebsite.com向providerwebsite.com发送一个请求
mywebsite.com收到回复
mywebsite.com向providerwebsite.com发送第二个请求
mywebsite.com收到回复
...
mywebsite.com向providerwebsite.com发送第十个请求
mywebsite.com收到回复
我想要发生的是（异步）：
访问mywebsite.com并填写表格
mywebsite.com向providerwebsite.com发送一个请求
mywebsite.com向providerwebsite.com发送第二个请求
mywebsite.com收到对第一个请求的响应
...
mywebsite.com向providerwebsite.com发送第十个请求
mywebsite.com收到对第九个请求的回复
mywebsite.com重新开始放弃对第十个请求的回复
以上只是一个例子 - 响应应该能够异步到达任何订单的
。问题是，每个请求最多需要800美元到800美元才能响应，10个同步请求时间= 8秒......方式太多
长...这个想法是如果我可以异步发送所有十个请求，
结果应该开始更快地返回。

如果是2.0，你也可以尝试使用WebClient对象的Async方法...
AFAIK如果外部服务器看不到这些请求属于同一会话的
（除非你做一些特别的事情，可能就是这种情况），
它应该工作。我不认为你在自己的服务器上会有这个限制
（因为你的服务器充当外部网站的客户端）。

If 2.0 you could also try the Async methods of the WebClient object...
AFAIK if those requests are not seen by the external server as belonging to
the same session (which is likely the case unless you do something special),
it should work. I don''t think you''ll have this limitation on your own server
(as your server act as a client to the external web site).

正如你所说，这是一个IIS限制。它与ASP.NET无关。
唯一的ASP.NET关系是你可能没有调用Dispose on
你的代理对象，所以你没有关闭连接。
John
It is an IIS limit, as you say. It has nothing to do with ASP.NET.
The only ASP.NET relation is that you probably aren''t calling Dispose on
your proxy objects, so you''re not closing the connections.
