Save link url as variable

[esoteric]

Hi.

I have a sort of security script which checks a few things, how can i save the url of the link that was clicked, so i can pass it through the script then if all is good, continue on to the url, if not send them somewhere else

 

let me try to explain better with a little text picture

 

user clicks link ----------------------> link goes to my security script --------------------> if the check passes, continue to original links url

 

so basically i just need to know how to save the links url as a variable

You could use ajax that posts the url in a variable or have a database that links an ID to a url (in this case, you link to a PHP page with the ID in the url). I would use ajax, cause it would be possible with javascript to intercept link clicks, determine the link being clicked, use ajax to call a PHP page to check the URL, then redirect the page if it is acceptable.
