SOAP HTTP Binding
The HTTP Protocol
HTTP communicates over TCP/IP. An HTTP client connects to an HTTP server using TCP. After establishing a connection, the client can send an HTTP request message to the server:
POST /item HTTP/1.1
Host: 189.123.345.239
Content-Type: text/plain
Content-Length: 200 |
The server then processes the request and sends an HTTP response back to the client. The response contains a status code that indicates the status of the request:
200 OK
Content-Type: text/plain
Content-Length: 200 |
In the example above, the server returned a status code of 200. This is the standard success code for HTTP.
If the server could not decode the request, it could have returned something like this:
400 Bad Request
Content-Length: 0

SOAP HTTP Binding
A SOAP method is an HTTP request/response that complies with the SOAP encoding rules.
HTTP + XML = SOAP
A SOAP request could be an HTTP POST or an HTTP GET request.
The HTTP POST request specifies at least two HTTP headers: Content-Type and Content-Length.
Content-Type
The Content-Type header for a SOAP request and response defines the MIME type for the message and the
character encoding (optional) used for the XML body of the request or response.
Syntax
Content-Type: MIMEType; charset=character-encoding |
Example
POST /item HTTP/1.1
Content-Type: application/soap+xml; charset=utf-8 |
Content-Length
The Content-Length header for a SOAP request and response specifies the number of bytes in the body of the request or response.
Syntax
Example
POST /item HTTP/1.1
Content-Type: application/soap+xml; charset=utf-8
Content-Length: 250 |
