Properties
The string that defines the begining boundary of our multipart transfer as defined in the w3c specs. This method also sets the Content and Ending boundaries as defined by the w3c specs.
public string BeginBoundary { get; set; }Allows us to determine the size of the buffer used to send a piece of the file at a time out the IO stream. Defaults to 1024 * 10.
public int BufferSize { get; set; }Allows us to specifiy the certificate to use for secure communications.
public X509Certificate Certificate { get; set; }Gets or sets a value indicating whether the file can be sent in smaller packets.
public bool Chunked { get; set; }The string that defines the content boundary of our multipart transfer as defined in the w3c specs.
public string ContentBoundary { get; set; }Allows us to specified the credentials used for the transfer.
public ICredentials Credentials { get; set; }The string that defines the ending boundary of our multipart transfer as defined in the w3c specs.
public string EndingBoundary { get; set; }Gets or sets a value indicating whether the Expect100-Continue header should be sent.
public bool Expect100 { get; set; }Used to change the content type of the file being sent. Currently defaults to: text/xml. Other options are text/plain or binary.
public string FileContentType { get; set; }Gets or sets a value indicating whether to make a persistent connection to the Internet resource.
public bool KeepAlive { get; set; }Gets or sets a value indicating whether to pipeline the request to the Internet resource.
public bool Pipelined { get; set; }The data returned to us after the transfer is completed.
public StringBuilder ResponseText { get; set; }Allows you to specify the specific version of HTTP to use for uploads. The dot NET stuff currently does not allow you to remove the continue-100 header from 1.1 and 1.0 currently has a bug in it where it adds the continue-100. MS has sent a patch to remove the continue-100 in HTTP 1.0.

public void Dispose()Implements:
Creates the proper ending boundary for the multipart upload.
Builds the proper format of the multipart data that contains the form fields and their respective values.
Make the request to the web server and retrieve it's response into a text buffer.
public void GetResponse()Determines if we have a file stream set, and returns either the HttpWebRequest stream or the file.
public Stream GetStream()Either the HttpWebRequest stream or the local output file.
Transmits a file to the web server stated in the URL property. You may call this several times and it will use the values previously set for fields and URL.
Allows you to add some additional field data to be sent along with the transfer. This is usually used for things like userid and password to validate the transfer.
Used to signal we want the output to go to a text file verses being transfered to a URL.
