Non-Web Links and Protocols

Linking to other web pages using the HTTP protocol is by far the most common type of link, but there are several other types of transactions that can be made using other standard Internet protocols.

Mail Link (mailto:)

The mailto protocol can be used in an anchor tag to automatically send an email message to the recipient, using the browser’s email application or an external email application. Note that the browser must be configured to support this tag, so it will not work for all users. The mailto protocol has the following components:

mailto:username@domain

mailto:username@domain?subject=subject 
mailto:username@domain?cc=person1
mailto:username@domain?bcc=person2 
mailto:username@domain?body=body

mailto:username@domain?subject=subject&cc=person1&body=body

<A HREF="mailto:jen@oreilly.com?subject=Like%20your%20book">Email ...
