# The idea is to do a HEAD request on a large file on an apache server with multiple byte ranges in multiple connections. | |
# The server then will have to read this large file from all the given byte ranges without returning any content | |
# (as it is a HEAD) request. If we do this about > 500 times in parallel the memory will collapse with | |
# the apache process crashing down. | |
