The URL Access Manager provides routines that allow your application to download data from or upload data to a Universal Resource Locator (URL) using four protocols: the Hypertext Transfer Protocol (HTTP), the secure Hypertext Transfer Protocol (HTTPS), the File Transfer Protocol (FTP), and the file:/// protocol.
In addition, the URL Access Manager provides firewall support, with support for HTTP proxy servers and for SOCKS gateways.
The high-level URL Access Manager functions for downloading and uploading data include options that allow you to specify the display of a progress indicator and the display of an authentication dialog box if authentication is required.
The URL Access Manager includes support for automatic decompression of compressed files. If version 4.0 of the Stuffit Engine is installed, the URL Access Manager also automatically extracts files from Stuffit archives.
The URL Access Manager defines a set of URL properties. Extensions can define additional properties and set their values.
