Abstract A new URL scheme, "finger", is defined. It allows client software to request information from finger servers that conform to RFC 1288. Description Many Internet hosts publish information through the finger protocol, as described in RFC 1288. In order to allow that information to be located in a standard fashion, a "finger" URL is needed. The "finger" URL has the form: finger: where is any request that conforms to the query specification given in RFC 1288. The interpretation of the finger request should be left to the receiving host. Clients sending finger queries should never send CR or LF characters. All requests must be sent to the standard TCP finger port, 79 (decimal). The client should look for requests that do not conform to RFC 1288 and reject them. Encoding RFC1738 requires that many characters in URLs be encoded. This affects the finger scheme in that some requests may contain space (" ", ASCII hex 20) and forward slash ("/", ASCII hex 2F). These characters must be encoded in the URL following the rules in RFC 1738. Examples Typically, a finger URL will be something like: However, note that RFC 1288 also permits requests such as: and: Security RFC 1288 contains a detailed section on both client and host security that should be read by anyone implementing clients that allow the finger URL. Specifically, client software should check for any unsafe characters and character strings before displaying the results of a query. Author contact information: Paul E.
