Abstract: A built-in apparatus, a HTTP request distribution method, a recording medium for storing a program to implement the method, and a Web system are disclosed. The built-in apparatus includes a first distribution part distributing a process corresponding to a HTTP request to a Web application associated with an application path of URL in the HTTP request and a second distribution part distributing the process to a process function associated with a URL path of the URL in the Web application. According to the present invention, it is possible to not only prevent performance reduction by decreasing workloads on a server program due to association of URLs with process functions but also provide various controls based on information other than URL.
