DefaultProxy   Download   Properties Methods Events Returns or sets whether the FTP/HTTP request will be asynchronous. Async   Return or set the HTTP authentication mode to use. Auth   Returns or sets if the stream is blocking. Blocking   Return or set the preferred receive buffer size, between 0 and 512 KB. BufferSize   Returns or sets the byte order used to read or write binary data to the stream. ByteOrder   Returns the HTTP Status Code sent by the server. Code   Return or set the file that will be used for reading and storing cookies. CookiesFile   Return or set the debugging mode. Debug   Return the number of bytes that have been downloaded. Downloaded   Return or set the "Accept-Encoding" HTTP header. Encoding   This property signals whether the last use of LINE INPUT reached the end of file, instead of reading a full line with an end-of-line character. EndOfFile   Return or set the newline separator used by this stream. EndOfLine   Return if a stream reached its end. Eof   Return the error string associated with the error code returned by the curl library. ErrorText   Returns the system file descriptor associated with this Stream. Handle   Return the HTTP headers as a String array. Headers   Return if a stream is associated with a terminal. IsTerm   Returns a virtual object that allows you to enumerate a stream line by line. Lines   Return or set if strings are null-terminated when they are serialized. NullTerminatedString   Returns or sets the password used for authorization. Password   Returns a virtual object used for defining proxy parameters. Proxy   Return the HTTP reason string. Reason   Return or set if the HttpClient must follow HTTP redirections. Redirect   This virtual property allows to define the SSL properties of the CURL connection. SSL   Returns the status of the client. Status   Returns or sets the tag associated with the stream. Tag   Return or set the target file used for download operations. TargetFile   Return a virtual object that allows to manage the terminal associated with the stream. Term   Returns or sets the client timeout in seconds. Timeout   Returns the total number of bytes that are expected to be downloaded. TotalDownloaded   Returns the total number of bytes that are expected to be uploaded. TotalUploaded   Return or set the URL of the resource to download. URL   Return or set if cookies must be updated. The default value is False. UpdateCookies   Return the number of bytes that have been uploaded. Uploaded   Returns or sets the user used for authorisation. User   Returns or sets the UserAgent used to make the request. UserAgent   Start to buffer data written to the stream, so that everything will be sent when the Send method is called. Begin   Closes the stream. Close   Fill the HttpClient object from the properties of another HttpClient object. CopyFrom   Drop the data that has been buffered since the last call to the Begin method. Drop   This method performs a call to the http server using the standard 'GET' method. Get   This method performs a call to the http server using the standard 'HEAD' method. Head   Returns the contents of the internal stream buffer. Peek   This method performs a call to the http server using the standard 'POST' method. Post   Send a file through a POST request. PostFile   Send some data to a specific URL by using the "PUT" method. Put   Send a file through a PUT request. PutFile   Read a line of text from the stream, like the LINE INPUT instruction. ReadLine   Send all the data, in one shot, since the last call to Begin. Send   Aborts the request. Stop   Start or stop watching the stream file descriptor for reading or writing, after it has been opened. Watch   This event is raised when a request has been cancelled. Cancel   Raised when the connection is established. Connect   Raised when there was an error returned by the CURL library. Error   Raised when a command terminates correctly. Finished   This event is raised periodically when something is downloaded or uploaded. Progress   Raised when there is some data received. Read

Example #2

This second example shows how you can download a file from the internet asynchronously.

It calls the DownloadAsync method with your URL. Then, when the download is completed, it displays the received HTML in the Finished event handler.
