How We Detect Installations of vBulletin


A CMS will sometimes include a meta tag within the html of each page. This is usually a "generator" tag like <meta name="generator" content="What CMS" /> but could also be "application-name", "Powered-By" or anyting else the CMS creators decide to use.


HTTP headers can provide some of the best clues about a site's CMS. The values of set-cookie and x-powered-by headers are the most common and easiest to find.


If a CMS doesn't have meta tags, it will often have other uniquely identifiable html markup. This can range from unique html comments, ids or classes.


Similar to identifiable html markup, a CMS will sometimes insert unique Javascript code into web pages.


In addition to detecting the CMS, in some cases we are able to accurately detect which version of the CMS is being used.
