This script makes http requests in order to discover valid user- specific directories and infer valid usernames. By default, the script will use Nmap's 'nselib/data/usernames.lst'. An HTTP response status of 200 or 403 means the username is likely a valid one and the username will be output in the script results along with the status code (in parentheses). This script makes an attempt to avoid false positives by requesting a directory which is unlikely to exist. If the server responds with 200 or 403 then the script will not continue testing it. SYNTAX: userdir.users: The filename of a username list. limit: The maximum number of users to check. http-max-cache-size: The maximum memory size (in bytes) of the cache. http.pipeline: If set, it represents the number of HTTP requests that'll be pipelined (ie, sent in a single request).
