INFORMATION PROCESSING APPARATUS, NETWORK SYSTEM, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

An information processing apparatus includes a memory that stores, on a per webpage basis, an assumed response pattern representing a document structure of a response to be generated by a web server in response to a webpage browsing request, through parsing of an assumed description of the response, a generation unit that generates a response pattern representing a document structure of a response generated by the web server in response to a webpage browsing request from a client, through parsing of a description of the response, and a transmission controller that performs control such that if the response pattern generated by the generation unit matches a form of an assumed response pattern stored in the memory in association with a target webpage of the webpage browsing request from the client, the response generated by the web server in response to the webpage browsing request is transmitted to the client.
