WebExcpetion由于并发事务太多？ [英] WebExcpetion due to too many concurrent transactions?

问题描述

我在IIS中运行了一个Web服务。

一个简单的ConnectionTest（）方法只需等待Thread.Sleep一秒钟，然后返回一个我写了一个小的测试应用程序，它启动了许多并行线程。每个线程调用Web服务方法，然后只输出到控制台。

现在我想通了，如果正好有10个线程同时调用ws，那么在这段时间内每个其他线程的startet都会从中获取WebException。网络服务。只要其中一个工作线程完成（并且少于10个线程同时调用ws方法），一个新线程就可以成功执行ws方法。

令我恼火的是，WebException说：请求失败，HTTP状态为403：禁止访问。

*）为什么我可以建立与ws的10个连接？

*）我可以更改/更改的位置（打开）客户端，在服务器上，配置文件...）这个设置？

*）WebException可能是由另一个问题引起的，并且可能想到多个并发连接是错误的？

如果有人能帮助我，那将是很棒的，因为我已经花了几个小时进行实时搜索和谷歌解决这个问题。

谢谢，

Christian

Hi,

i have a web service running in IIS.

A simple ConnectionTest() method just waits with Thread.Sleep for a second and then returns a string.

I've written a small test application, that starts a number of parallel threads. Each thread calls the web service method and then just outputs to the console.

Now i figured out, that if exactly 10 threads are concurrently calling the ws, each other thread startet during that time gets a WebException from the web service. As soon as one of the working threads finishes (and less than 10 threads are concurrently calling the ws method), a new one can successfully execute the ws method.

what irritates me is, that the WebException says: The request failed with HTTP status 403: Access Forbidden.

 *) Why can i establish exactly 10 connections to the ws?

 *) Can i change/where chan i change (on client, on server, which config file...) this setting?

 *) May the WebException be caused by another problem, and may idea with to many concurrent connections is wrong?

It would be great, if anyone could help me, since i already spent hours on live search and google to solve this issue.

Thanks,

Christian
