#
# aFleX script to present a Sorry Page with images in local cache.
#
# 1) Upload the image to the cache using the following command;
# "import local-uri-file <local-file-name> [use-mgmt-port] [username <name>] <path>"
# For example:
# import local-uri-file logo.jpg use-mgmt-port ftp://ftp@192.168.1.23/images/logo.jpg
#
# 2) Create a RAM Cache template that references the image (as local-uri)
# For example:
# slb template cache tp-cache
#    policy local-uri /logo.jpg
#
# 3) Apply the RAM template AND aflex to the vPort;
# For example:
# slb virtual-server vip1 192.168.4.251
#   port 80  http
#      template cache tp-cache
#      aflex sorry-page
#
# Scalability of this aFleX is unknown.
