HTTP

Kodi contains an HTTP-client with which you can add sources in all sections in the Kodi interface.

HTTP/HTTPS url format
Kodi supported normal http/https urls, additionally, it support optional options we called as 'protocol options' which user/addons can set so that Kodi can full simulate the browser operations with specified http request header values. http[s]://[username[:password]@]host[:port]/directory/file?a=b&c=d
 * normal http url format:

http[s]://[username[:password]@]host[:port]/directory/file?a=b&c=d|option1=value1&option2=value2
 * http url with 'protocol options':

Kodi supported special http protocol options
which is required if your HTTP server uses any type of authentication other than basic (which is, in fact, unsafe unless used over HTTPS). E.g. if your HTTP server uses digest authentication, use. For maximum flexibility, use  or   (i.e. anything other than basic).
 * auth

when the media url is unseekable, addons can set  protocol options, then Kodi won't try to seek on that url. if you set it in frodo or earlier, it will add a http header ' ' in the http request, it's harmless.
 * seekable (13.0+ Gotham, since git bb79b32b)

Other http protocol options (they are all rfc defined http request headers)

 * Referer
 * User-Agent
 * Cookie
 * Encoding
 * any other http request headers defined in rfc.

For the meanings of these, see RFC 2616.
