The requested FTP command is not supported when using HTTP proxy

    I am trying to upload files on FTP and used the code below:

    Dim request As FtpWebRequest

    request =
    request.Method = WebRequestMethods.Ftp.UploadFile
    request.Credentials = New
    NetworkCredential(ftp_site_user_name, ftp_site_password)

    Dim sourceStream As New
    StreamReader("C:\Documents and Settings\.......\text.txt")

    Dim filecontents() As Byte =

    request.ContentLength = filecontents.Length

    Dim requestStream As Stream =
    requestStream.Write(filecontents, 0,

    When I define to use proxy (in Interent options/connections/LAN
    settings) I receive an error "The requested FTP command is not
    supported when using HTTP proxy". When I define NOT to use proxy, the
    file is transfered on FTP.

    1. Is there a way for defining to bypass the proxy for this ftp
    connection ?

    2. Can I create subdirectories on FTP from code ?

    3. StreamReader reads TXT files. How can I read ZIP files for uploading
    on FTP ?

    Thanks a lot.

  2. Hi Chirs,

    I am having the same problem. Did you find a solution?

    I am new in asp and I also have problems with this exception:

    "The requested URI is invalid for this FTP command"

    I paste the URI in windows explorer and I don't have any problems.

    Any ideas?

    Thanks a lot

    will solve the problem if you can edit the code.

    if you don't have the access to the code then
    remove the use proxy check in internet explorer settings.
