Abstract:
1. A method for collection, comprising: receiving at a first server a first request for content that is associated with a first URL from a requesting computing resource; collecting click-through information from a first header of said first request, the click-through information comprising information related to the first request; sending a URL redirect command comprising a second URL associated with a second server to said requesting computing resource causing said computing resource to issue a second request for said content from the second URL; including said click-through information in a domain name of said second URL in said URL redirect command enabling transfer of said click-through information to a third party auditing server supporting domain name resolution for said second URL without establishing a connection between said third party auditing server and any server providing said content; receiving a DNS query for said domain name of said second URL at said third party auditing server from said requesting computing resource, wherein said domain name includes subdomains comprising a delimiter separating a string of the click-through information and a sub-level domain of a corresponding domain name; parsing said click-through information from said domain name of said second URL at said third party auditing server; and responding to the DNS query by sending an IP address for said domain name of said second URL from said third party auditing server to said requesting computing resource without establishing a connection between the third party auditing server and any server providing the content.
