Active Link Security

I am no longer giving support for this hack. Use this hack: https://vborg.vbsupport.ru/showthread.php?t=95753 instead. You can take my redirector page and use it though.

Thanks to TC from ElAntro.cl for the PHP code.

Active Link Security 5.2

This hack will allow you to have active links on your forum but with security knowing the place were you are linking to wont know were you users came from. IE. If you click on a link in a post on your web site, the web site you go to will not know were you came from.

Time: < 30 seconds

Files to upload: 1


For vb 3.0.x version: https://vborg.vbsupport.ru/showthread.php?t=70684


No screenshots needed. Also, please click ?install? if you use.

Hmm... Interesting. Does this in effect act as an outlink filter? Part of why I ask is that if someone posts http://www.website.com it is interpreted as an outgoing link to the Google spiders and most other SE scrapers, but if they come across a dynamic link such as link.php?url=http://www.website.com, it doesn't get indexed as an outlink, and will help your PR.

Is that what this mod does? If not, maybe I'm misunderstanding the purpose of this.

I'm not sure what your saying.

What I know this DOES do is does not let the web site you go to know were you came from. Lots if notall web site keep track of were users came from. The hack will prevent them from knowing the people came from your web site.

Here is an example:

Click here. Look at: "You linked from here (if you linked from another web page):"

Now, click here. Now look again there.

Right, I see what you are saying. I have a feeling that I'm correct about what I posted above. This is a good hack if it works out like I think it will. I'll do some SE testing with it and see what I can come up with. If I have favorable results, I'll let you know.

I was just thinking about this script, it would be a nice addition to add click tracking to it. Where when someone clicks an outgoing link from your site, the script logs the click, and where you can view different traffic stats in the AdminCP.

OUT CLICKS:
25 http://www.google.com
12 http://www.yahoo.com
10 http://www.vbulletin.org

etc...

Possibly browser sniffing, resolution tracking etc...
Just an idea.

Since the recommended code to find does not appear in RC1 you should look for this:

// standard URL hyperlink

and add the replacement code above it. At least this is how I got it to work.

Yes, this is correct although I will be looking into make this hack a plugin.

Looking at this code, I had to take a double look. What the hell is this? Then I figured it out. Your a clown!

I just started looking though the code for a way to do it. Your sounds great but too easy. I'll look around a drop more before releasing something.
