Async HttpWebRequest + AutomaticDecompression Stack Overflow Exception

标签： c# multithreading httpwebrequest gzipstream

我正在对传统网络服务（asmx）进行故障排除，以验证合作伙伴网站上的价格。我们最近打开了HttpWebRequest.AutomaticDecompression标志（DecompressionMethods.Deflate | DecompressionMethods.GZip），希望能够加快某些大型（650K +）页面合作伙伴的响应速度。代码是旧的和专有的，因此很难发布示例，因此我将尝试提供一些实现亮点：

  • 在4.5应用程序池中运行的旧版.NET 3.5 ASMX Web服务（允许TLS 1.2）
  • 每个请求（可能）产生多个工作线程;每个合作伙伴都要检查一次。

  • 工作线程使用自动解压缩创建HttpWebRequest，并使用异步方法等待合作伙伴响应：

    IAsyncResult r =（IAsyncResult）wreq.BeginGetResponse（new AsyncCallback（RespCallback），rs）;

由于进入我们的测试环境，结果是获得了一些成功的响应，然后是应用程序池中的硬崩溃。迷你转储显示由处理压缩流引起的堆栈溢出（显然）：

我最初的问题：

  1. 在4.5应用程序池中运行3.5个应用程序是否存在固有问题？使用VS2008进行3.5运行时调试时，此问题不会重现。
  2. 这是一个已知问题的症状（解压缩非压缩数据或长度不匹配吗？）...看到BeginReadWithoutValidation不会激发信心。

    3. 我意识到这很模糊，所以请让我知道我可以添加哪些细节。
