MAILTO

 The mailto URL is used to  send electronic mail. If the browser supports mailto URLs, when a link that contains one is selected, the browser will prompt you for a subject and the body of the mail message, and send that message to the appropriate address when you’re done. Depending on how the user’s browser and email client are configured, mailto links might not work at all for them.

The mailto URL is different from the standard URL form. It looks like the following:

mailto:internet-e-mail-address

here’s an example:

mailto:lmmay@1ne.com

NOTE

If your email address includes a percent sign (%), you’ll have to use the escape character %25 instead. Percent signs age special characters to URLs.

Unlike the other URLs described here, the mailto URL works strictly on the client side. The mail to link just tells the browser to compose an email message to the specified address. It’s up to the browser to figure out how that should happen. Most browsers will also let you add a default subject to the email by including it in the URL like this:

mailto:lemay@1ne>com?subject=hi there!

When the user clicks on the link, most browsers will automatically stick Hi there! In the subject of the message. Some even support putting body text for the email message in the link like this:

mailto:lemay@1ne.com?subject=Hi there!&body text.

USENET NEWSGROUPS

Usenet was URLs have one of two forms:

News:name-of=-newsgroup

News:message-id

The first form is used to read an enter nets group, such as c9omp.infosystems. www.authorisng .html or alt. gothic. if your browser supports Usenet news URLs (either directly or through a newsreader). It’ll provide you with a list of available articles in that newsgroup.

The second form enables you to retrieve a specific news article. Each news article has a unique ID, called a message ID, which usually looks something like the following:

1emayct76jq.cwG@netcom.com

To use a message ID  in a URL, remove the angle brackets and include the news: part: news: 1emayct76jq.cwG@netcom.com

Be aware that news articles don’t exist forever-they expire and are deleted. So, a message ID that was valid at one point can become invalid a short time later. If you want a permanent link to a news article, you should just copy the article to your web presentation and link it as you would any other file.

Both forms of URL assume that you’re reading news from an NNTP server, and they can be used on if you have defined an NNTP server somewhere in an environment variable or preferences file or your browser. Therefore, news URLs are most useful simply for reading specific news articles locally, not necessarily for using in links in pages.
