Hi, We could try and implement this functionality of resuming broken downloads like in some softwares like Download Accelerator and bit-torrent.
I hope my views can help, so here goes:- When a file is being downloaded, we can keep a stack of all of these downloads in progress at a centralized repository, preferably where the user has kept his file hosted for download or on the machine where the download is to be done. Next, we can keep the track of the point at which the download stopped and store it in the repository. Next, if the user tries to start the download it again, we can again retrieve it back from the data and get the end point of the previous download. The end point for each file can include the file details in terms of bits and bytes( 0 & 1) or even in percentages or pieces..Next time we can break our file based on pieces or percentages( as needed) and start the download from the nearest point that is best suited for the user. I hope this helps... I request your feedback... Thanks, Jitesh Dundas Mobile- +91-9860925706 http://jiteshbdundas.blogspot.com On 8/9/08, Carsten Aulbert <[EMAIL PROTECTED]> wrote: > Hi > > Perry E.
