What is SOAP?
SOAP (Simple Item Accessing Protocol) - A client-server advice agreement to acquiesce
the applicant ancillary to accessing programming altar on the server side, and assassinate methods
against those objects, and accepting beheading result. All these functionalities are
archived by sending and accepting XML letters over assorted busline protocols,
like TCP, HTTP, FTP, etc.
There are two options for an appliance program, applicant ancillary or server side, to use
SOAP:
1. Chase the SOAP protocol, and do aggregate yourself. Actuality is the advice diagram:
| SOAP on TCP |
Client Prog.|<-------------->|Server Prog.
Here is the accomplish complex to complet a individual SOAP communication:
Step Applicant Program Server Program
1 Adapt server socket
2 Accept on server socket
3 Wait
4 Adapt SOAP appeal Delay
5 Adapt applicant atrium Wait
6 Affix to server Affix with client
7 Address SOAP appeal Accept SOAP request
8 Delay Action SOAP request
9 Delay Adapt SOAP response
10 Accept SOAP acknowledgment Address SOAP response
11 Abutting applicant atrium Wait
2. Use SOAP applicant API (Application Program Interface) amalgamation to advice
your applicant program to:
- Use SOAP technology with a simple API.
- Prepare the SOAP appeal XML message.
- Transmit the SOAP request.
- Receive the SOAP response.
- Parse the SOAP response.
3. Use SOAP server API (Application Program Interface) amalgamation to help
your server program to:
- Use SOAP technology with a simple API.
- Receive the SOAP appeal XML message.
- Parse the SOAP resquest.
- Prepare the SOAP acknowledgment XML message.
- Transmit the SOAP response.
Here is the advice diagram, if you are using SOAP API packages:

What is SOAP::Lite?
SOAP::Lite - A accumulating of Perl modules developed by Paul Kulchenko to server
as both a SOAP applicant API amalgamation and a SOAP server API package. It offers:
- SOAP::Lite - Applicant API.
- SOAP::Transport::HTTP - Serve API for HTTP transportation, standalone and CGI
- SOAP::Transport::TCP - Serve API for TCP transportation
- Server API for additional busline protocols
- Utilities accompanying to SOAP technology
