/// This function implements the Web Proxy Auto-Discovery (WPAD) protocol for automatically configuring the proxy settings for an HTTP request. The WPAD protocol downloads a Proxy Auto-Configuration (PAC) file, which is a script that identifies the proxy server to use for a given target URL. PAC files are typically deployed by the IT department within a corporate network environment. The URL of the PAC file can either be specified explicitly or WinHttpGetProxyForUrl can be instructed to automatically discover the location of the PAC file on the local network.

ERROR_WINHTTP_INCORRECT_HANDLE_TYPE - The type of handle supplied is incorrect for this operation.

ERROR_WINHTTP_LOGIN_FAILURE - The login attempt failed. When this error is encountered, close the request handle with WinHttpCloseHandle. A new request handle must be created before retrying the function that originally produced this error.

ERROR_WINHTTP_OPERATION_CANCELLED - The operation was canceled, usually because the handle on which the request was operating was closed before the operation completed.

This function implements the Web Proxy Auto-Discovery (WPAD) protocol for automatically configuring the proxy settings for an HTTP request. The WPAD protocol downloads a Proxy Auto-Configuration (PAC) file, which is a script that identifies the proxy server to use for a given target URL. PAC files are typically deployed by the IT department within a corporate network environment. The URL of the PAC file can either be specified explicitly or WinHttpGetProxyForUrl can be instructed to automatically discover the location of the PAC file on the local network.

WinHttpGetProxyForUrl must be called on a per-URL basis, because the PAC file can return a different proxy server for different URLs. This is useful because the PAC file enables an IT department to implement proxy server load balancing by mapping (hashing) the target URL (specified by the lpcwszUrl parameter) to a certain proxy in a proxy server array.

I tested this method in sync method, it is ok. But according to MSDN and C++ code, the second param should be NULL when use async method. This function cann't work.

fExpectResponse (in) A Boolean value that indicates whether the application expects a data connection to be established by the FTP server. This must be set to TRUE if a data connection is expected, or FALSE otherwise.

the structure I used in this structure information page.

        IntPtr hInternet,

    public static extern long InternetCloseHandle(IntPtr hInet);

        : this()

        GC.SuppressFinalize(this);

Another way to say it, this one in VB style:

Use one or more of these flags to control file caching:

Dim changed As Boolean = FtpSetCurrentDirectory(hINetConn, changePath)

  __in  HINTERNET hConnect,

  ' This code is for VB 2002 or newer. For VB 6, replace "Integer" with "Long".

There are noted problems from some users using this function when the computer is behind a proxy.

static extern bool InternetCloseHandle(IntPtr hInternet);

    ByVal hInet As IntPtr) As <MarshalAs(UnmanagedType.Bool)> Boolean

   IntPtr hInternet, string lpszServerName, short nServerPort,

    ByVal hInternetSession As System.IntPtr,

hInternetSession

    Number of the TCP/IP port on the server to connect to. Can be one of the values in the following list. If this parameter is set to INTERNET_INVALID_PORT_NUMBER, the function uses the default port for the specified service. These values do not cause the function to use this protocol. The value sets the port to be used. A flag must be used to set the service.

    Address of a null-terminated string that contains the name of the user to log on. If this parameter is NULL, the function uses an appropriate default, except for HTTP. A NULL parameter in HTTP causes the server to return an error. For the FTP protocol, the default is anonymous.

    INTERNET_SERVICE_FTP     INTERNET_CONNECT_FLAG_PASSIVE (Use passive mode in all data connections for this FTP session.)

Having a connect function for all protocols, even those that do not use persistent connections, lets an application communicate common information about several requests using a single function call. In addition, this allows for future versions of Internet protocols that do not require a connection to be established for every client request.

For maximum efficiency, applications using the Gopher and HTTP protocols should try to minimize calls to InternetConnect and avoid calling this function for every transaction requested by the user. One way to accomplish this is to keep a small cache of handles returned from InternetConnect; when the user makes a request to a previously accessed server, that session handle is still available.

To close the handle returned from InternetConnect, the application should call InternetCloseHandle. This function disconnects the client from the server and frees all resources associated with the connection.
