Hi, Now I have eventually found an example again for the wrong progress bar output when continued output is started again at the beginning. It isn't exactly the case I had seen before with internal restarts, actually it is even simpler and the wrong output is more obvious.
First the protocol: wget -c http://www.somehost.com/somefile.jpg --18:58:58-- http://www.somehost.com/somefile.jpg Resolving localhost... 127.0.0.1 Connecting to localhost|127.0.0.1|:3128... connected. Proxy request sent, awaiting response... 200 OK Length: 157962 (154K) [image/jpeg] The sizes do not match (local 150780) -- retrieving. --18:58:59-- http://www.somehost.com/somefile.jpg Connecting to localhost|127.0.0.1|:3128... connected. Proxy request sent, awaiting response... 200 OK Length: 157962 (154K) [image/jpeg] Saving to: `somefile.jpg' 51% [=============================> ] 157,962 5.37K/s in 3m 45s 19:02:53 (702 B/s) - `somefile.jpg' saved [157962/157962] One can see that it had only a rest of about 7K to transfer but started at the beginning again. The file is transferred correctly, but the output looks "weird". it is neither the correct output for a continued transfer nor the correct output for a complete transfer. Further examination of such cases showed that a Byte-Range transfer was requested by wget, but was not done by the server. On most normal cases this cannot happen, because wget first examines the headers and does these requests only when they are advertized by the server. The situation, where this does happen nevertheless, is very complicated and rare and envolves local and remote proxies again. The server here seems to do some load-balancing with several hosts (multiple IP-numbers per DNS) and when also a local proxy is in between, it can happen that every HTTP-request lands on a different host with possibly different behaviour and it can happen that we have another case of a discrepancy between the result of a HEAD and a later GET.
