varnishtest "Composite HTTP manipulation test (H1 and H2 clear to H1 clear)"
#REQUIRE_VERSION=1.9

# This config tests several http-request features and their interactions.
# It extracts some samples, places them into variables, modifies some header
# fields, appends multiple identical header fields, overwrites the start line
# using several methods, then dumps the initial list of variables and the final
# one, then applies CRC32 to these values as signatures that are easy to test.
# Then it does it again in the backend after saving the current headers into
# the same names prefixed by "fe-". Then it does the same on the response path.
# If some modifications are performed, the crc values need to be adjusted based
# on the failed logs.
#
# Run it with HAPROXY_PROGRAM=$PWD/haproxy varnishtest -l -k -t 1 "$1"
