Any of you web (HTML) gurus know if it's possible to put a redirect into the HEAD of a page that will only redirect certain IP address (or visitors from certain domains)?

I have a few pages that the FAA and Delta are using A BUNCH (users from xxx.faa.gov and xxx.delta.com on the server log) and I'd prefer that they didn't use so much of my bandwidth. Could I set up a redirect that would send only those IP/domains to say a porn site or something to make their work day a little more exciting?

I'm guessing it can be done, kinda like a browser sniffer action but look at the IP instead. I'm just not sure if it would be embedded in the page, or a SSI, or?

Thanks -

 

Pretty easy to do with server side programming, and depending on what kind of server side technology you're using, I might be able to help you.

If your site is all static html, you'll still be able to do it via JavaScript. But visitors could just turn off javascript to get around your redirect, though.

 

use php or somethin...or you could use mod_rewrite if you're on apache

 

The pages are static HTML, no databases here. Using JavaScript, could I put an action in the HEAD of the page to do the redirect? Am I on the right track?

Thanks for the help!

 

Thanks Josh, you urged me to learn php a while back....and I never did.

Maybe someday, I'll have the time (and mentors) to figure it out.

No love for my ASP :-(

I don't know if php is the same, but you'll have their IP address, you may have to filter via that, and not the domain itself.

 

I'm assuming SSI works on your webserver. If so, try this:

[CODE]

<script language="javascript">

var strRedirectURL = "http://www.goatse.cx";

var strRemoteHost = "";

var arrBannedDomainsRE = [/^.+.faa.gov$/g, /^.+.delta.com$/g];



for (var i = 0; i < arrBannedDomainsRE.length; i ++) {

 

Too Cool! Thanks!

SSI do work on my server, so I added the script and no problems viewing the pages (any other errors) so far.

Thanks Again!

 

Can the same script use for filtering or redirecting IE and Netscape users?

You mean will the script in both IE and Netscape? I think so, though I haven't tested it with Netscape.

If you mean you want to allow only users of browsers other than IE and Netscape to visit your site, you'll have to modify it slightly.

Also keep in mind that:
1. Person from faa.gov and delta.com will still be able to hit your homepage once before getting redirected. So while the number of hits from that domain will hopefully be reduced, it won't be eliminated.
2. The script does not prevent search indexing bots from visiting your site still (thus if that's the source of your increased bandwidth usage, this won't solve your problem)
3. Someone can turn off javascript on their browser to work around this script.

To truly block someone would require some server side work - modifying web server configuration, for instance.
