SUMMARY
To access a file on a secured FTP server, that is, a server that does not accept anonymous requests, the protocol requires that the username and password be supplied as a part of the uniform resource locator (URL) used to make the request. The format of such a URL is the following:

ftp://: @/



MORE INFORMATION
To demonstrate the usage of this syntax using Internet Explorer, follow these steps:
 * 1) Identify an FTP site that requires a username and password and a file on that server that you wish to get.
 * 2) Launch Internet Explorer.
 * 3) In the Address combo box enter the URL in the format specified above.

The contents of the file should be display in the Browser window.

To demonstrate the syntax using a URL moniker, follow these steps:
 * 1) Build the Progress sample included with the Internet Client SDK.
 * 2) Run the Progress sample specifying the same address used in step 3 above.

The contents of the file should display in the Progress dialog box.

Developers using URL monikers should observe that the requirements for obtaining secured data via the FTP protocol is different from the requirements for obtaining secured data via HTTP. To use a URL moniker to bind to secured data stored at an FTP site, the host must supply the URL moniker with the username and password in the initial call to CreateURLMoniker in the format specified above.

To use a URL moniker to bind to data stored on an HTTP server, the host implements IAuthenticate on the same object that implements IBindStatusCallback. The URL moniker calls the host's implementation of IAuthenticate::Authenticate to retrieve authentication information.
