IndySoap is a Open Source Library for implementing Web services using Delphi/CBuilder Compilers. IndySoap isn't tied to Indy for transport services, though Indy based transport services are included.
*RPC and Doc|Lit support
*Soap using Interfaces
*Extensively DUnit tested
*many other things
IndySoap is a fantastic library for implementing RPC for Application Servers and Web Services using SOAP. There is nothing as fast and as reliable and as easy to implement and Mantain. Forget HTTPRIO, Native Delphi SOAP, REM Objects and everything else. You won't find anything better....
