Is it possible to only allow sites to be accessed from certain sites?

Would it be possible to set up a web page so that it could only be accessed when coming from a specific site.

Example:
RandomWebPage.com could only be access when coming from adminaddict.net.

?

Or could a cookie be set indicating that RandomWebPage.com was accessed from adminaddict.net?



As always feel free to move this Nick : )

 

I believe this is done via .htaccess file such as the following:

Code:

# Allow from the website
rewritecond %{HTTP_REFERER} "^http://(www)?\.mydomain\.com/.+$"
RewriteRule ^(.*)$ $1 [L]

 

Thanks!

I know nothing about .htaccess files, could that be put in a subdirectory or subdomain?

adminaddict.net/SpecialPage or SpecialPage.adminaddict.net?

But access to adminaddict.net would not be affected?

 

Correct, you can put a .htaccess file (ascii) into any directory you wish.

 

Of course, be aware it is easy to fake the referrer and many anti virus / internet security apps actually remove it.

 

good input, thanks.

Someone else mentioned 'deny all' then, allow from www.referringsite...

Can anyone tell me where that might be accomplished? cPanel? Ftp?
