Holds all the information needed to read or write on a directory of an internet server. I am used for FTP and HTTP (and STMP? NNTP?). The password policy is: unless it is a public password (like annomyous), clear all passwords before any snapshot. There is a way to store passwords on the disk. server 'www.disney.com' or '123.34.56.08' or the ServerDirectory above me (if I am a subdirectory sharing the info in a master directory) directory 'ftp/pubs/' name of my directory within the server or superdirectory. (for file://, directory is converted to local delimiters.) type #ftp what you can do in this directory user 'Jones45' password an instance of Password. group an Association ('group name' -> an array of ServerDirectorys) If this first one is down, try the next one. Store on all of them. I am in the list. moniker 'Main Squeak Directory' Description of this directory. altURL When a FTP server holds some web pages, the altURL of those pages is often different from the FTP directory. Put the altURL here. If the directory is 'public_html/Squeak/', the altURL might be 'www.webPage.com/~kaehler2/ Squeak/'. urlObject An instance of a subclass of Url. It is very good at parsing complex urls. Relative references. file:// uses this. Use this in the future instead of server and directory inst vars. socket nil or an FTPSocket. Only non-nil if the connection is being kept open for multiple stores or retrievals. loaderUrl a partial url that is ised to invoke squeak in a browser and load a project. A normal call on some command like (aServer getFileNamed: 'foo') does not set 'socket'. Socket being nil tells it to close the connection and destroy the socket after this one transcation. If the caller stores into 'socket', then the same command does NOT close the connection. Call 'openKeepFTP' or 'openGroup' to store into socket and keep the connection open. It is up to the user to call 'quit' or 'closeGroup' later. DD openKeepFTP. Transcript cr; show: ((DD getFileNamed: '1198misc-tkKG.cs') next: 100).

HTTPSockets support HTTP requests, either directly or via an HTTP proxy server. An HTTPSocket saves the parse of the last ASCII header it saw, to avoid having to parse it repeatedly. The real action is in httpGet:accept:. See the examples in the class, especially httpFileInNewChangeSet: and httpShowGif:.!

A Socket represents a network connection point. Current sockets are designed to support the TCP/IP and UDP protocols Subclasses of socket provide support for network protocols such as POP, NNTP, HTTP, and FTP. Sockets also allow you to implement your own custom services and may be used to support Remote Procedure Call or Remote Method Invocation some day. JMM June 2nd 2000 Macintosh UDP support was added if you run open transport. !

This class implements TCP/IP style network name lookup and translation facilities. Attempt to keep track of whether there is a network available. HaveNetwork true if last attempt to contact the network was successful. LastContact Time of that contact (totalSeconds). haveNetwork returns true, false, or #expired. True means there was contact in the last 30 minutes. False means contact failed or was false last time we asked. Get out of false state by making contact with a server in some way (FileList or updates).!

This class supports client for simple network protocols based on sending textual commands and responses. Examples of such protocols include POP3 (mail retrieval), SMTP (mail posting), HTTP (web browsing), and NTTP (network news). Some simple examples are presented as class methods, but a full-service client of some service should be implemented as a subclass. The basic services provided by this class are: sendCommand: -- sends a command line terminate with <CR><LF> getResponse -- gets a single-line response to a command getMultilineResponse -- gets a multiple line response terminated by a period -- on a line by itself There are variants of the getResponse commands that display lines on the screen as they are being received. Linefeeds are stripped out of all responses. The 'get' commands above make use of an internal buffer. So intermixing these two commands and regular Socket recieve commands can cause problems.!

A Socket represents a network connection point. Current sockets are designed to support the TCP/IP and UDP protocols. Sockets are the lowest level of networking object in Squeak and are not normally used directly. SocketStream is a higher level object wrapping a Socket in a stream like protocol. ProtocolClient and subclasses are in turn wrappers around a SocketStream to provide support for specific network protocols such as POP, NNTP, HTTP, and FTP.!
