Information processing system and communication retry method

A program of causing an information processing apparatus to function as the following sections, comprising:

• a communication log analysis section for extracting, from communications including a series of communication messages exchanged between a client and a server, a first parameter of a request given to the server from the client and a second parameter of an element that has generated the request and is included in a response given from the server to the client before the response, maintaining the first parameter when the first parameter value and the second parameter value differ from each other, and maintaining the description indicating the second parameter when the first parameter value and the second parameter value are identical to each other;
• and
• a communication definition generation section for generating a request definition in which the value the communication log analysis section maintains is set as the parameter value corresponding to the value.

A program of causing an information processing apparatus having a storage section in which communication definition information including a series of requests to be sent to a server is stored, the communication definition information being associated with bookmark IDs, and an arithmetic processing section, to carry out:

• a processing in which the arithmetic processing section, when receiving a third request including a bookmark ID from a client, reads the communication definition information associated with the bookmark ID from the storage section, sends the first request of a series of requests included in the communication definition information to the server, and sequentially sends the remaining requests of the series of requests to the server each time receiving a response from the server;
• and
• a processing in which the arithmetic processing section sends a response of the server relative to the last request of the series of requests to the client.
