Difference between SOAP and HTTP protocol?, What is difference between soap and http protocols?..thanks in advance. styloa August 30, 2014, 2:30pm #2. SOAP will commonly run on top of  To interact with server, request should be in XML encoded format using SOAP. But in case of HTTP, request can be sent in HTML, Image, video format etc. SOAP request are sent using HTTP protocol. SOAP stands for Simple Object Access protocol. It is XML based used for sending and receiving messages.

Difference between soap and http protocols - Get Started, While SOAP and REST share similarities over the HTTP protocol, SOAP is a more rigid set of messaging patterns than REST. The rules in SOAP  SOAP, REST, ODATA and HTTP protocols are the most important current Web service APIs.. HTTP - HTTP is the native transport layer protocol that can carry plain, soap, json or ODATA messages. For simplicity, we can assume it to be the Father of transport protocols with Children like SOAP, REST and ODATA

SOAP stands for Simple Object Access protocol. It is XML based used for sending and receiving messages. It is defined with in XML.

Example.
<?xml version="1.0"?>

<soap:Envelope
xmlns:soap="http://www.example/2003/05/soap-envelope/"
soap:encodingStyle="http://www.example.com/2003/05/soap-encoding">

<soap:Body>
  <m:GetPriceResponse xmlns:m="http://www.example.com/prices">
    <m:Price>1.90</m:Price>
  </m:GetPriceResponse>
</soap:Body>

</soap:Envelope> 

smtp stands for Simple Mail Transfer Protocol. Simple Mail Transfer Protocol is a way to transfer email reliably and efficiently. smtp is used to send mail to the recipient's mailbox,thus using various methods to access the emails in his mailbox. smtp by default uses tcp port 25. The protocol for mail submission is the same, but uses port 587. smtp connections secured by [SSL], known as smtps, default to port 465 (nonstandard, but sometimes used for legacy reasons). We can send messages synchronously or asynchronously. Sessions can be automatically managed.

SOAP is language dependent, But SMTP is Language independent. SOAP is mainly used for XML webservices. SMTP is also using http protocol to get or post information.

Understanding SOAP vs REST: Basics And Differences, There is huge difference between REST and SOAP. SOAP SOAP builds an XML based protocol on top of HTTP or sometimes TCP/IP. SOAP  Only difference is in message structure. Soap uses HTTP as transport protocol. Soap supports web service security features such as Reliable messaging, assertion and so and http wont. REST webservice (light form) supports HTTP.

SOAP vs REST: Simple Object Access Protocol Vs , The main differences between SOAP and REST; What does REST and sends back responses through internet protocols such as HTTP,  SOAP (abbreviation for Simple Object Access Protocol) is a messaging protocol specification for exchanging structured information in the implementation of web services in computer networks.

SOAP vs REST vs JSON, Thanks for your post. HTTP is a communications protocol that transports messages over a network. SOAP is a protocol to. exchange XML-based  HTTP is a communications protocol that transports messages over a network. SOAP is a protocol to exchange XML-based messages that can use HTTP to transport those messages.

Difference between soap and http protocol in web service, Difference between SOAP, REST, ODATA and HTTP protocols. Advantages, Disadvantages and Differences between Widely-Used Web Service Communication  Both SOAP and REST have issues to consider when deciding which protocol to use. The Similarities While SOAP and REST share similarities over the HTTP protocol, SOAP is a more rigid set of messaging patterns than REST.

  • HTTP is over TCP, not over TCP/IP, TCP/IP is the whole stack which includes the application layer(SOAP in the the application layer). You can't say the SOAP sits over something that includes SOAP.
  • HTTP is over TCP and IP. In the OSI model, TCP is in the transport layer and HTTP (and SOAP) is in application layer. See en.wikipedia.org/wiki/OSI_model. But that doesn't change the answer. Just a like a roof sits on top of a house, SOAP is layered on HTTP. You can argue a roof and a house are in the same layer, but the roof is still on top of the house.
  • @Ireeder When we say TCP/IP, it is no longer the OSI model of 7 layers but the TCP/IP Protocol Stack of 4 layers. Here "On top of" should mean that one is immediately included in the other.
