Unformatted text preview: r concurrent servers, one that forks a new process for each request, the other that creates a new thread for each request. Other designs are possible, such as using the Unix select function to explicitly manage the concurrency, or avoiding the per-connection overhead by pre-forking a set of child processes to handle connection requests. Finally, we studied the design and implementation of a simple but functional Web server. In a few lines of code, it ties together many important systems concepts such as Unix I/O, memory mapping, concurrency, the sockets interface, and the HTTP protocol. Bibliographic Notes The official source information for the Internet is contained in a set of freely-available numbered documents known as RFCs (Requests for Comments). A searchable index of RFCs is available from http://www.rfc-editor.org/rfc.html RFCs are typically written for developers of Internet infrastructure, and thus are usually too detailed for the casual reader. However, for authoritative information, there is no better source. There are many texts on computer networking [41, 55, 80]. The great technical writer W. Richard Stevens developed a whole series of classic texts on such topics as advanced Unix programming [72], the Internet protocols [73, 74, 75], and Unix network programming [77, 76]. Serious students of Unix systems programming will want to study all of them. Tragically, Stevens died in 1999. His contributions will be greatly missed. 12.9. SUMMARY The authoritative...
