Unless you are really dead set on using IDHttp, there are a few other alternatives for you. I have a component based on WinInet (the same library that Internet Explorer uses for downloading urls) that works very well. It runs async, so it does not block your UI thread. You can set any number of urls's to be downloaded, and the wininet library handles the thread management side of things; you only need to handle the event portion of the component. The downloads can be cancelled at any time, and you can also specify a timeout if you wish them to auto terminate after a set time. If you are interested:

example usage:

let me know if you have any questions. (my french is a little rusty though)
