Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To simplify the processing when the same processing request comes from a request source concerning a computing system for performing processing on the basis of the processing request transmitted through a network and replying the processing result to the computer of the request source. SOLUTION: A session managing server 32 prepares an area for embedding error information in a communication protocol for transmitting the processing result to the request source. When there is an error in the processing result, the error information is preserved together with the processing result, the error information is embedded in the communication protocol, and the processing result is transmitted to a Web client 100. When the same processing request comes from the Web client 100 again, according as whether the error information is embedded in the communication protocol or not, it is judged whether the last processing result is normal or error. When the last processing result is normal, the last processing result is transmitted to the request source but when there is an error in the last processing result, processing is performed again.
