# The server_names_hash_bucket_size seems to prevent long domain names!
# The default, according to nginx's docs, depends on "the size of the
# processors cache line." It could be as low as 32. We fixed it at
# 64 in 2014 to accommodate a long domain name (20 characters?). But
# even at 64, a 58-character domain name won't work (#93), so now
# we're going up to 128.
