Ocamlnet

Internet protocols (http, cgi, email etc.) and helper data structures (mail messages, character sets, etc.)

Ocamlnet implements a number of Internet protocols (http client & server, cgi and cgi variants, SunRPC, FTP, POP, SMTP) and is a strong base for web and Internet programming. Many protocols can even be driven in an asychronous way, since Ocamlnet defines a framework for asynchronous implementations (equeue). There is also a generic server framework (netplex). There are a number of accompanying data structures like mail messages, URLs, buffers, channels, and also routines for character set conversions.

In particular, Ocamlnet consists of these libraries:

• netstring is about processing strings that occur in network context. Features: MIME encoding/decoding, Date/time parsing, Character encoding conversion, HTML parsing and printing, URL parsing and printing, OO-representation of channels, and a lot more.
• netcgi1 and netcgi2 focus on portable web applications. netcgi1 is the older, backward-compatible version, whereas netcgi2 bases on a revised design, and is only partly backward-compatible. Supported are CGI, FastCGI, AJP (mod_jk), and SCGI.
• nethttpd is a web server component (HTTP server implementation). It can be used for web applications without using an extra web server, or for serving web services.
• rpc implements ONCRPC (alias SunRPC), the remote procedure call technology behind NFS and other Unix services.
• netplex is a generic server framework. It can be used to build stand-alone server programs from individual components like those from netcgi2, nethttpd, and rpc. Several such components can be mixed in a netplex setup.
• netclient implements clients for HTTP (version 1.1, of course), FTP (currently partially), and Telnet.
• equeue is an event queue used for many protocol implementations. It makes it possible to run several clients and/or servers in parallel without having to resort to multi-threading or multi-processing.
• shell is about calling external commands like a Unix shell does.
• netshm provides shared memory for IPC purposes.
• netsys contains bindings for system functions missing in core O'Caml.
• smtp and pop are two further client implementations for the SMTP and POP3 protocols.
