ASMX Web服务方法帮助页面上的SOAP消息是什么？

Question

I am currently studying Web Services and after doing a sample practise in a.asmx file, I notice that below the sample method output page, there's many SOAP related messages like the ones below, can anyone tell me what are these messages for? Thanks.

SOAP 1.1 The following is a sample SOAP 1.1 request and response. The placeholders shown need to be replaced with actual values.

POST /SecurityWebService/Service.asmx HTTP/1.1
Host: localhost

Content-Length: length
SOAPAction: "http://tempuri.org/GetSecurityInfo"

<?xml version="1.0" encoding="utf-8"?>

These are messages encoded in the SOAP protocol. .NET kinda puts that in a "black box" that for you, so that you don't have to handle SOAP messages creation and parsing yourself.
