The present invention relates to a TCP / IP communication network browser apparatus and an information storage medium for browsing a homepage through a Web browser on a data receiving side in an Internet, an intranet, an extranet, or the like that performs data communication using an ontrol protocol / Internet protocol.

[0002]

2. Description of the Related Art Conventionally, on the Internet, an intranet, an extranet (hereinafter, only the Internet) for performing data communication using TCP / IP, a homepage is browsed through a Web browser on a receiving side. When browsing this website, the URL (U
niform Resource Locator) to access the web page directly. Access to such Web pages may be restricted.

[0003] On the Internet, for example, if the sending side is W
Access to an eb page from an undesired country may be restricted. In addition, in intranets that are frequently used by companies, regulations may be made so that only the home page can be viewed for each section. Web on these sending side
Restrictions on page access include, for example, Microsoft's W
RSACi (Rec
reational Software Advisory Councl rating service
Regulation services are known. In this case, the creator of the content (outgoing information) writes the “PICS rating tag” on his / her homepage, the Web browser interprets the “tag”, and displays information based on this format. When information related to regulation is written as a "tag" on this homepage, transmission of the homepage is regulated.

[0004] As described above, on the Internet, the rank to be regulated can be specified on the receiving side, but the sending side cannot specify the rank.
Since the regulation of the web page is ranked, it cannot be said that effective regulation can always be performed. In addition, regulations are limited to what is considered harmful, preventing effective use of the Internet. For example, when a distance learning company rents out a small general-purpose computer for the Internet for distance learning with the use of its communication line free, etc., users may access other than the distance learning homepage provided by the distance learning company. Doing so would result in unexpected charges for using the communication line for the distance learning business.
