Cross Domain Tracking

Hi,

I have three sites (domain1, domain2 and domain3).
Currently, a user clicks a button on domain1 to start their journey, they are then sent to domain2. On domain2 the user clicks a button to complete their journey.

This is what I want to do, when the user clicks the button on domain1 to start their journey, a cookie is saved from domain3 and when the user clicks the button on domain2 to complete their journey the cookie on domain3 is updated.

I know cross domain cookies are an issue however i've heard of people using the image <img> to get round this problem by placing a hidden image on the pages where the button is and setting it's src in script (possibly php).

I also need to send the cookie info to a database but thats the easy bit.

Any ideas??

Take a look here, good luck with this. As long as you are aware of the risks of doing so: http://www.phpbuilder.com/columns/c...gs20001128.php3

Thanks for the reply, can this not be done in asp.net??

It appeared to me above that you were looking for a PHP solution, as you stated:



I'd imagine you could perform similar thing in ASP.Net using URL rewriting. You'd simply have to convert the PHP code to the VB.net or C# equivalent, for example. Basically, the script I provided a link for is creating global variables, creates a cookie, writes the new URL to the page, and then allows for URL rewriting on all domains. Here is an example of URL rewriting in .Net: http://www.codeproject.com/aspnet/URLRewriter.asp

I don't have time to rewrite the php code for you, but you should be able to get the basic idea on your own.

Hi and sorry, i haven't provided enough information on this. I had seen a solution in php but i know nothing about it, again appologies for not being clear enough.

The two sites are domain1 asp.net web application and domain2 perl web booking application.
Currently, a user clicks a button on domain1 to start their journey, they are then sent to domain2. On domain2 the user clicks a button to complete their journey.

Thanks again for your help here
