Referrer's

Is there a way to block certain referrer's....someone put a link to my site on another site that I don't want it on....is there a way to block that referrer?

Thanks in advance.

Not unless you do your own detection of the referrer in javascript and redirect the logic elsewhere.

Can you point me someplace that tells me how to do it or tell me here o something of the like?

You can add a ascript like this in the <head> portion of your page if you want all the links to all come in from your site only:

Or to block links coming in from another site, just by reversing the test:

For instance I set up the test to ban a referrer not from my own site at http://widget.webado.com/test-ip-ban/test-referrer.html . It will accept if you test http://widget.webado.com/test-ip-ban...referrer1.html however.

http://widget.webado.com/test-ip-ban...referrer2.html shows a ban on http://my.statcounter.com as referrer.

None of this works for non-javascript enabled browsers or, naturally, if the user just copies the link and uses it directly in the browser.

Also the tests may be different for different browsers, this works in IE, not sure about Firefox or others.

Actually it works in Firefox as well.

This is another case where mod_rewrite might help. I've been trying -- so far unsuccessfully -- to do something with the referer information.

In the course of investigating that, I came across this tidbit which might provide a partial solution to your problem:

Quote:

RewriteCond %{HTTP_REFERER} ^http://members.asianavenue.com/I_am_that_guy/$
RewriteRule ^/pics/house/DCP00047-320.jpg$ /images/babyshit.jpg [P]

You'd need to modify the RewriteRule (maybe use ^(.*)$ as the left-side value. And I haven't tested this and have been unable to get a similar thing to work so far, but it's worth a try if you're comfortable mucking with such a bizarre Unix "feature".

Better not. Too dangeorus. The .htaccess file is very delicate and can mess things up royally if not handled properly. Besides many hosts don't allow using one or modifying it anyway. It can interfere with FrontPage extensions for instance. And it's either not available or doesn't work in the same way on windows servers in any case.

Good point. And I did try to indicate the it should be done only by someone who feels comfortable with such things.

The standard redirects in .htaccess are fairly simple and easy enough to set up -- and not all that dangerous. I use it to set a custom error page and to handle bad search-engine information, taking users from the ancient pages Yahoo used to serve up to something similar and current. It's a far more elegant and a faster solution than using meta redirects or something similar that depends on client-side processng.

mod_rewrite, on the other hand, is both tricky and dangerous, but also very powerful. I use it now only to create a canonical host name, converting everything that isn't www.ttca.org into that name. What I'm trying to do now is also redirect several requests that have been coming in from Google's non-US image results. It doesn't work yet, but I think I'm a good enough tester to both notice and overcome the problems that arise.

Works on Mozilla Suit also, so the script can't be to old

What if you remove the "alert" part from the script, does it work then?
Seams to me that it would be much more fun to redirect the visitor from a banned site directly to an other site, without the alert. I can imagine certain kind of sites I would use to make the banned sites owner look really dirty minded
