Can't do it. The external link will go to the other server. Your server won't
even know it happened.

And you should ask in alt.html. This isn't a PHP question (since PHP is
server-side only).

Re: Speed Bumps

This isn't PHP, but you'd probably want to use JavaScript.
Try something like this (attributes removed for readability):

<html>
<head>
<script>
function speedBump(){
/*---------Code to delay exit--------*/
}
</script>
</head>
<body onunload="speed Bump()">
</body>
</html>

You're trying to slow down the people who are "leaving" by
second-guessing them? (Metaphors are fun but can mislead: I can
follow an external link without "leaving" your page.) In a world where
people are always in a rush, standing in their way could well earn you
a punch in the nose!

Re: Speed Bumps

I think a better option would to use framing, have your own top frame saying
it aint your website, and maybe a link to go back to your website. An
option?

Yep -- don't do it. It can be done quite easily with PHP, but if I were
on your site and ran into your "speed bump", I doubt I'd be back. If I
clicked the link in the first place, that's where I want to go. Making me
click again is only going to be annoying.

Actually, upon further consideration, I can think of a situation where it
might be valid, if you want to make it clear that the visitor is leaving
your site, and you have no connection with the site they're going to. For
example, if you were writing an article on hate groups, and wanted to
link to some of their sites.

So, just write a script that takes a URL in the query string, display
your warning, and output the URL in a link. Then link to that in your
article or whatever.

But if it's just for, "Aww, shucks -- are you sure you want to leave my
excellent site????" -- don't do it. You will be regarded with contempt by
your visitors.

Another valid reason would be a (more or less secure) "logged in" area, and
displaying a warning you're leaving that area.
It could be done in PHP, but it would mean converting all your links, which
is a hassle. A quick temporary solution would be to turn on outbut
buffering, and searsching replacing links with preg_replace(). It's not
something I'd choose as a permanent solution though, it's unneccesary extra
memory and processing compared to doing it correctly.

It's a common practice for government sites. The idea is that people
need to know they will no longer be looking at official information.

There is also a security dimension. Such a page helps ensure that
you're not leaking sensitive information through the HTTP referrer
field.

Just one more example of what an appaling incompetent mess the HTML world
is.

sigh.

The idea sounds fine to me, and I would even extend it further than
government webpages. I would have *all* links as clear as possible, so
that the relationship between the current page and the linked-to one is
obvious. (Unless there is some reason to obscure that relationship;
none spring to mind.)

I would still take issue with the setting up of a middle page to
achieve that end though, but from a user's perspective I can't offer
much in the way of argument other than my own opinion that it would be
a nuisance being presented with an 'are you sure?' (said in a Mrs Doyle
from /Father Ted/ voice) each time I followed an external link.

Besides, external links can be set apart in other ways. For example,
the title attribute of the link (e.g., title="EXTERNAL LINK: ... "),
the rel attr. (e.g., rel="external", with a suitable Profile), the
surrounding text (e.g., explain in the prose what the link is), and the
style of the link (e.g., an image after every external link). Those
can be combined to make the relationship between the two pages more
explicit.

Good call, hadn't thought of that. RFC2616 mentions it.

I think we would need to distinguish intra- from internet then.

Perhaps the middle page could be used to describe the external link in
more detail so the user can decide if it's worth the time to load the
page. The javascript option I posted can descibe in more detail the
external link, graphic intensive, only suitable for a articular browser
etc... or the other option is a middle page, and that doesn't require
anything more advanced than standard html 4.01.

But obviously there is a valid use for an option to decline loading the
external link.

why not just have target="blank" in the HTML - that way they still have
your site
