A system in which a personal computer sends messages into a TCP/IP network using a conventional dial-up link and downloads data from the TCP/IP network using a high-speed one-way satellite link. A preferred embodiment uses a conventional SLIP provider to connect to the TCP/IP network and uses a commercial software TCP/IP package that has a standard driver interface. A spoofing protocol compensates for the long propagation delays inherent to satellite communication.

The access controller of claim 10, wherein one of the access control mechanisms comprises an access control list (ACL) of user information and the privileges that are associated with a particular resource. 15. The access controller of claim 10, wherein one of the access control mechanisms comprises a third party access control mechanism that controls access to resources that are not managed by the web server. 16. The access controller of claim 10 further comprising a user interface configured to present a user with one or more user-selectable security scenarios. 17. A web server comprising: a plurality of access control mechanisms, each access control mechanism being configured to control access to the web server or to resources that are used by the web server, and having one or more settable security settings; and a plurality of security scenarios each being associated with one or more security settings of one or more access control mechanisms, the security scenarios being selectable by a user to automatically set the security settings of the one or more access control mechanisms with which the security scenario is associated. 18. The web server of claim 17, wherein one of the access control mechanisms comprises an authentication mechanism for authenticating various users. 19. The web server of claim 17, wherein one of the access control mechanisms comprises a web permissions mechanism that defines what particular operations are allowed on particular resources. 20. The web server of claim 17, wherein one of the access control mechanisms comprises an access restriction mechanism that can permit or deny access to a web site based upon an identification that is associated with a particular user. 21. The web server of claim 17, wherein one of the access control mechanisms comprises an access control list (ACL) of user information and the privileges that are associated with a particular resource. 22. The web server of claim 17, wherein the plurality of access control mechanisms comprise at least two of the following: an authentication mechanism for authenticating various users; a web permissions mechanism that defines what particular operations are allowed on particular resources; an access restriction mechanism that can permit or deny access to a web site based upon an identification that is associated with a particular user; and an access control list (ACL) of user information and the privileges that are associated with a particular resource. 23. A method of synchronizing access control in a web server comprising: selecting a location within a hierarchical namespace, the location being associated with accessible resources; presenting a user with an option to inherit security settings from an upstream location in the hierarchical namespace, the security settings setting security for a plurality of access control mechanisms that control access to a location's accessible resources; and inheriting the security settings from the upstream location responsive to a user opting to do so. 24. The method of claim 23 further comprising presenting the user with an option to select from one or more security scenarios, each security scenario being associated with one or more security settings for a plurality of access control mechanisms that control access to resources associated with the web server. 25. The method of claim 23, wherein one of the access control mechanisms comprises an authentication mechanism for authenticating various users. 26. The method of claim 23, wherein one of the access control mechanisms comprises a web permissions mechanism that defines what particular operations are allowed on particular resources. 27. The method of claim 23, wherein one of the access control mechanisms com
