Internet Download Manager reuses available connections without additional connect and login stages to achieve better acceleration performance.

Internet Download Manager supports proxy servers, ftp and http protocols, firewalls, redirects, cookies, authorization, MP3 audio and MPEG video content processing.  You can also drag and drop files, or use Internet Download Manager from command line. Internet Download Manager can dial your modem at the set time, download the files you want, then hang up or even shut down your computer when it’s done.
