#REGTEST_TYPE=devel

# This reg-test uses the "del ssl crt-list" command to remove a line from a crt-list.

# It performs three requests towards a frontend that uses simple.crt-list.
# Between the second and third requests, a line is deleted from the crt-list,
# which makes the third request fail since it would have used the deleted line
# and the strict-sni option is enabled on the frontend.
# Another test is performed as well. A line corresponding to the default instance
# of a frontend that does not have the strict-sni option enabled cannot be deleted.
