Overview

The New X Window System presents complete and authoritative information on X11R6.4, the new X Window technology that enables enterprise systems--both legacy and newly developed--to run over the Internet. Code-named Broadway, this powerful technology holds many advantages for organizations. It enables X applications to move seamlessly from LANs to WANs to the Internet without the need to rewrite or even recompile, saving enterprises many thousands of dollars. Broadway also allows users access to enterprise programs from anywhere on the Internet, offers a consistent application interface--whether inside or outside a firewall--and greatly improves the performance of X applications. Geared for architects, designers, developers, and administrators, The New X Window System introduces X11R6.4, highlights its many advantages, and shows how to harness the technology to the greatest advantage. Readers will find a detailed description of the X11R6.4 architecture, its various components, migration, and the administration tasks required to enable an enterprise application to execute remotely via the Internet. The book also offers a comparison of Broadway to other Internet solutions, most notably Java(TM). Specific topics covered include: *The rationale behind X11R6.4 and its evolution from earlier X technology *Broadways low-bandwidth X (LBX) technology for enhancing performance *X11R6.4 HTTP/HTML extensions *Web server and browser administration *X11R6.4 security, including access control lists (ACLs) and magic cookies *Interoperability with Java and the Microsoft Terminal Server Written by a leading authority on X, The New X Window System demonstrates Broadways complete Internet solution--one that is easily deployed and maximizes an organizations investment in its information technology.
