Response not of type text/xml: text/html

昨晚把delphi　soap 编译为IndyHttp 问题一样，编写个NuSoap客户端竟然也返回

Response not of type text/xml: text/html

也许是我写的服务器端有问题，因为只有正常才会返回xml头，抽空再检查吧！
网上找了些资料也没解决：

• Making calls to a Web Service Often Results in invalid Content-Type Error
• IIS 6 Soap expects text/xml
• 用Delphi编写WebService的心得体会.
• Re: SOAP Protocol version
• NuSOAP and WSDL
