You can set the begin of partial download and the end. When you not send the end, then all from the begin to filesize was downloaded. Your server must support partial content! --------------------------------------------- Thomas Wegner Cabrio Meter - The Weather Plugin for Trillian http://trillian.wegner24.de/cabriometer "Ralf Hoffmann" <"ralf$"@tmx.de> schrieb im Newsbeitrag news:41962de3 (AT) newsgroups (DOT) borland.com...

Yes, but only if the server supports HTTP v1.1. If so, then you can assign the ContentRangeStart and ContentRangeEnd subproperties of the TIdHTTP.Request property prior to calling Get(). The ContentRangeStart and ContentRangeEnd subproperties of the TIdHTTP.Response property will be filled in accordingly to let you know what is actually transferred. If the server does not support content ranges, then the file will be transferred in full from the beginning again.
