Base structure.
Called on the IO thread when the browser needs credentials from the user. |isProxy| indicates whether the host is a proxy server. |host| contains the hostname and |port| contains the port number. Return true (1) to continue the request and call cef_auth_callback_t::cont() when the authentication information is available. If the request has an associated browser/frame then returning false (0) will result in a call to GetAuthCredentials on the cef_request_handler_t associated with that browser, if any. Otherwise, returning false (0) will cancel the request immediately. This function will only be called for requests initiated from the browser process.
Called when some part of the response is read. |data| contains the current bytes received since the last call. This function will not be called if the UR_FLAG_NO_DOWNLOAD_DATA flag is set on the request.
Notifies the client of download progress. |current| denotes the number of bytes received up to the call and |total| is the expected total size of the response (or -1 if not determined).
Notifies the client that the request has completed. Use the
Notifies the client of upload progress. |current| denotes the number of bytes sent so far and |total| is the total size of uploading data (or -1 if chunked upload is enabled). This function will only be called if the UR_FLAG_REPORT_UPLOAD_PROGRESS flag is set on the request.
Structure that should be implemented by the cef_urlrequest_t client. The functions of this structure will be called on the same thread that created the request unless otherwise documented.
