Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : Looking for a way to BLOCK a web page when it comes from a particular location

[wf19]

There's someone out there who has a web page of mine on their public profile. I don't want to be associated with this individual.

Using a service like Sitemeter it's possible to track where your hits are coming from.

Is it possible that to not only detect where a hit is coming from, but somehow block, or redirect (perhaps to another page that states "go away") when it comes from a specific location?

For example, if somone puts a link to my page on their profile at:
http://profiles.yahoo.com/(yahoo_ID_here)

Is it possible to reject or redirect the page by sensing where it comes from.

If previous page = x
then redirect to y
else, go to z

Is it possible to foward the page to another location if and only if it comes from a specific location or site?

Yes, you can do this. By using a script. Or perhaps Apache mod_rewrite could do this.

Could you please explain how I can do this? Where is this script/code? I'm very good with HTML, but I don't know what Apache mod_rewrite is.

Thanks.

I can't go into the details, but someone else will probably be able to...

Wouldn't it be easier and faster, since he knows where the traffic is coming from, to use a .htaccess file and the HTTP_REFERER var?

You're speaking in greek to me.

Is it possible to explain this in layman terms?

php, perl, asp, jsp, c, .htaccess, firewall, i dunno 403 their asses

Would someone please tell me how to do this?

I posted this on several forums. Here, Emaildiscussions.com, Sitepoint...

Someone on Craigslist did this for me

Have a look at this thread:

if applicable, just post your questions there -- helps to keep it together.

The above method uses .htaccess (tops in my book) but there a way to restrict access by using a JS script, that follows your method:

If previous page = x
then redirect to y
else, go to z

but, being JS, would require the code to be on every page -- not good. Using .htaccess you can apply restricting to every page on your Web site, with only a few lines of code in an .htaccess file.

Thanks, it appears the Craigslist method:

is working just fine for my needs.

That's tricky. You can't put code into a .jpg file

[Website Rob]

Weelll, if your hoster provides Cpanel (like some do ) then you have Anti-leech built in. If not, you can go the route of downloading a free/pay-for script (lots around at the script sites; look under: anti-leech) or using the .htaccess method with a RewritCond directive.

If you are not familiar with Apache directives, you are best to get in touch with your Hoster to see if/how they have Rewrite rules working.

Put this in a .htaccess-file and the bugger is history:

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://your_domain.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.your_domain.com/.*$ [NC]
RewriteRule .*\.gif$ - [F,L]

RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://your_domain.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.your_domain.com/.*$ [NC]
RewriteRule .*\.jpg$ - [F,L]

This will allow gifs and jpgs to be served if the HTTP_REFERER is your domain - and only you. Remember to add additional lines if you have parked domains and/or other subdomains than www!

Another less technical image (that I've actually seen done before) is to simply copy the image to another name, and change it on your site -- so if everyone was accessing, say, image.jpg, you would change your site to use image2.jpg. Then replace image.jpg with a blurry 1600x1200 picture of a tree or something... If the leechers are using it inline on their page, their site will look totally screwed up, and they'll quickly take the image down. (Be prepared for the site owner to be piping mad, but it's his own fault )

The .htaccess file probably works a lot better, but replacing the image is a lot more fun.
