The Solaris 2.6 release also included the ability to make a file system on the Internet accessible through firewalls. This capability was provided by using an extension to the NFS protocol. One of the advantages to using the WebNFSTM protocol for Internet access is its reliability. The service is built as an extension of the NFS version 3 and version 2 protocol. Also, an NFS server provides greater throughput under a heavy load than Hypertext Transfer Protocol (HTTP) access to a Web server. This throughput can decrease the amount of time that is required to retrieve a file. In addition, the WebNFS implementation provides the ability to share these files without the administrative overhead of an anonymous ftp site. See Security Negotiation for the WebNFS Service for a description of more changes that are related to the WebNFS service. See WebNFS Administration Tasks for more task information.
