LAST UPDATE: August 2017
In this series of blog posts, we’ve been looking at various ways in which servers present information which can be used by search engines to uniquely identify them. That is, they leave footprints, often very obvious ones. Here at EBN we take quite a few steps to make sure that the servers hosting our WordPress blogs don’t stand out from the crowd.
So far, we’ve talked about Server headers (these usually present the software powering the webserver, most commonly Apache), X-Powered-By headers (the technology running WordPress, usually a version of PHP), and ASN numbers (these are used to pinpoint the company hosting the server).
This time we’re taking a look at common server default pages which are returned when we enter a server’s IP into our browser. These are default pages which servers toss up when something’s gone wrong, like when a user clicks on a broken link (meaning it links to something that doesn’t exist, usually because a webpage has been moved or renamed) or a link meant for someone who is logged in to a specific service.
