Posting Acceptor provides a receiver for Microsoft IIS to accept files from clients using the HTTP multipart/form-data method to post their Web content. Clients using this posting method include the Web Publishing Wizard/API 1.5 Microsoft ActiveX™ Upload control and Netscape Navigator 2.02 or later. Posting Acceptor can also provide the same functionality to a cluster of servers with content managed through CRS supporting the Web Publishing Wizard/API 1.5 client. In this way, Microsoft Web Publishing Wizard/API and any HTTP Post–compliant clients, can post content through a standard firewall.
For example, suppose an Internet service provider (ISP) decides to host Web pages for its users. The ISP simply installs Posting Acceptor on its Web server and creates a virtual directory called "users." Users are then able to post their content to the server and retrieve it from a URL such as http://servername/users/username. A graphic representation of these relationships is provided in the following illustration.
