HOWTO: Use authentication protocols with Image Uploader

There is a mechanism allowing to get credentials (user name and password) when making a request to a site. In the case if this mechanism is enabled on a site, you get the dialog requesting login and password before loading the page. There are two basic authentication protocols: basic (.htaccess) and ntlm. Image Uploader supports both of them.

There is no need to do anything with Image Uploader ActiveX, it detects authentication type automatically. However Image Uploader Java requires to be initialized with authentication type used on the site where it uploads files to via its parameters. You can specify authentication mechanism used on your site via AuthenticationType property. If you initialize this property properly Image Uploader Java will show you the dialog where you will be able to enter login name and password. These credentials will be passed to HTTP POST request initialized by the applet to upload files.
