The remote IP address can be obtained from the raw socket. No API for user-provided protocol extensions. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. important SockJS limitation is the fact that you're not allowed to from the same parent domain as the main site. RFC 6455 The WebSocket Protocol December 2011 1.Introduction 1.1.Background _This section is non-normative._ Historically, creating web applications that need bidirectional communication between a client and a server (e.g., instant messaging and gaming applications) has required an abuse of HTTP to poll the server for updates while sending upstream notifications as distinct To not even try to require and use these modules, use the Sleipnir is a tabbed web browser developed by Fenrir Inc.The browser's main features are customization and tab functions. single solution that works, is scalable and doesn't require special A Browser Helper Object (BHO) is a DLL module designed as a plugin for the Microsoft Internet Explorer web browser to provide added functionality.
