Thanx for the hack but the I need a generic hack.
I am trying to build an opensource application which downloads a file 
partially using wget on different computers. Each computer synchronize 
download status using a centralized server.

Is it WGET not downloading the file or SEVER not sending the content? If 
its wget then we can fix it using a patch right ? So that it can 
download partial content even if file does not exists.
