Lua

HTTP Download any Type of File (binary or text)

See more HTTP Examples

The Download method can download any file type, whether binary (e.g., .zip, .pdf) or text (.xml, .txt), without distinction. It streams the file byte-for-byte from the web server exactly as received. This same process applies to web pages: providing a URL typically viewed in a browser downloads the server's delivered HTML to a file. Lua
