CPPSERV: Documentation: Communications protocol

Web server <-> application server communication

Communication protocol between web server and application server is fairly simple:

• Web server receives HTTP request
• Web server connects to the servlet engine
• Web server sends Servlet name, which it figures out through its own mapping system, followed by newline character
• Web server sends request line, followed by newline character
• Web server sends request headers, followed by empty line
• Web server sends request body
• Web server shuts down writing side of its socket
• Web server reads servlet output and processes it, just like it would do with any CGI script
