?-U agent-string? ?--user-agent=agent-string? Identify as agent-string to the http server. The http protocol allows the clients to identify themselves using a User-Agent header field. This enables distinguishing the www software, usually for statistical purposes or for tracing of protocol violations. Wget normally identifies as ?Wget/version?, version being the current version number of Wget. However, some sites have been known to impose the policy of tailoring the output according to the User-Agent-supplied information. While this is not such a bad idea in theory, it has been abused by servers denying information to clients other than (historically) Netscape or, more frequently, Microsoft Internet Explorer. This option allows you to change the User-Agent line issued by Wget. Use of this option is discouraged, unless you really know what you are doing. Specifying empty user agent with ?--user-agent=""? instructs Wget not to send the User-Agent header in http requests.
