Editing URL redirection (section)

=== Logging outgoing links ===
The access logs of most web servers keep detailed information about where visitors came from and how they browsed the hosted site.  They do not, however, log which links visitors left by.  This is because the visitor's browser has no need to communicate with the original server when the visitor clicks on an outgoing link. This information can be captured in several ways.  One way involves URL redirection.  Instead of sending the visitor straight to the other site, links on the site can direct to a URL on the original website's domain that automatically redirects to the real target. This technique bears the downside of the delay caused by the additional request to the original website's server. As this added request will leave a trace in the server log, revealing exactly which link was followed, it can also be a privacy issue.<ref name="NtrEdf" /> The same technique is also used by some corporate websites to implement a statement that the subsequent content is at another site, and therefore not necessarily affiliated with the corporation. In such scenarios, displaying the warning causes an additional delay.
