我正在研究通过 WCF Web 服务将大量数据上传到使用 HTTPS 的服务器的解决方案。我的基础设施设计是这样的：
客户端应用程序 <-- HTTPS --> ISA 服务器 <-- HTTP --> WCF Web 服务
Web 服务托管在 IIS6、Windows server 2003 上。我使用 basicHttpBindings。当我开始上传 2MB 的数据时，我收到： 向https://myservice.com/WcfService/service.svc/basic发出 HTTP 请求时发生错误。这可能是由于在 HTTPS 情况下未使用 HTTP.SYS 正确配置服务器证书。这也可能是由于客户端和服务器之间的安全绑定不匹配造成的
但是当我尝试上传 100Kb 时，一切正常。为什么？请有任何建议。
完整的异常消息：
System.ServiceModel.CommunicationException 未处理
Message=向https://myservice.com/WcfService/service.svc/basic发出 HTTP 请求时发生错误。这可能是由于在 HTTPS 情况下未使用 HTTP.SYS 正确配置服务器证书。这也可能是由于客户端和服务器之间的安全绑定不匹配造成的。
