title: How can I send bandwidth of client to server?
body: <p>Is there away for server (web-server of web-page or file server) to know what bandwidth client had during last access or during page/file request? Can this information be sent via cookie or together with page/file request?</p>
  
  <p>I guess this is more of theoretical question, since I want to know if server can provide lower resolution image for clients with bad bandwidth available to them.</p>
