What is a SOAP Request ?

I know that HTTP + XML = SOAP. Also i read that SOAP request is embedded with HTTP POST or HTTP GET.

Can anyone please explain me what is the relation between SOAP and HTTP Protocols.

i.e. In a request made from a client to a web method, How exactly the HTTP and SOAP protocals are used ? in What percentage ?

SOAP is an XML-based protocol for exchanging information between computers. SOAP can be used in a variety of messaging systems and can be delivered via a variety of transport protocols, the initial focus of SOAP is remote procedure calls transported via HTTP.

So its like HTTP is the one which is xfering the SOAP Message i.e. HTTP is a xfer protocol while SOAP is infomration exchange protocol.

We called HTTP as a Service transport while SOAP is respo. for XML Messaging.
