connection_info = chall_json["connection_info"] if len(connection_info) != 0: f.write("%s\n\n" % connection_info)

The second line above causes an exception and challenge files do not download. This seems to happen when connection_info == None.

Changed it to if connection_info != None and len(connection_info) != 0:

File Download Issue When Header Doesn't Include "Content-Length"

When parsing https://byu.ctfd.io, In line 120: size = int(r.headers["Content-Length"])

throws an error, because headers["Content-Length"] does not exist.

Commented that line and set size = 0

However, when investigating what size was being used for, I saw that it takes two paths in line 127. Was not obvious what the difference was between lines 128-131 and 133-136
