Web: URL Schemes

A series of RFCs document URL schemes based on a variety of protocols. These include:

RFC2255 (December 1996, The LDAP URL Format)

Enables web-style access to LDAP servers. For example, my entry in the Switchboard directory is accessible, from a browser, using the URL:

ldap://ldap.switchboard.com/cn%3DJon%20Udell%2C%20ou%3DZEDHINGL%2C%20o%3Dswitchboard%2C%20c%3DUS
RFC2192 (September 1997, IMAP URL Scheme)

Defines an imap: URL scheme that supports web-style references to objects (e.g., messages) that live on IMAP servers.

RFC2368 (July 1998, The mailto URL Scheme)

Extends the mailto: scheme defined in RFC1738, enabling the message composition and filtering techniques that we saw in Chapter 4 and Chapter 9.

RFC2384 (August 1998, The POP URL Scheme)

According to RFC2384, “A POP3 mailbox (like an [IMAP4] mailbox) is a network resource, and URLs are a widely supported generalized representation of network resources. A means of specifying a POP3 mailbox as a URL will likely be useful in many programs and protocols.”

Finally, here’s a bit of web trivia. If you store the following text in a file:
