I had a list of about 100 URLs to download, and it seemed to hang at
random. I'm not sure how long it would have continued to hang for, but
when I came back to my computer the first time, the current time for the
download was at around 25 minutes, and the file being downloaded should
have been downloaded in around 20 seconds, so I just quit the
command. Luckily, the files I was downloading were quite small, so I was
able to delete them and repeat the test quickly.

After writing to curl-users, I noticed an article in the mailing list
archives about the difference between using HTTP 1.0 and HTTP 1.1. This
gave me the idea to try passing the header "Connection: close". This seems
to have solved the problem. I can now download all of the URLs, and curl
exits successfully each time.

Thanks for your reply.
