Http class to irule conversion?

Hi mihaic,

just copy all classes (section from previous /config/bigip.conf) into a single file on your /shared directory and name it i.e. ./classes, please:

cat ./classes | tr -d "\r\n" | sed -r "s/(\})/\1\n/g" | \
sed -r -e 's/^[[:blank:]]+//g' -e 's/\}$/ }/g' | tr -s '[[:blank:]]' | \
sed -r 's/^profile httpclass ([^ ]+) \{ defaults from httpclass pool ([^ ]+) paths regex ([^ ]+) \}/ltm rule rule_\1 {\n  if { [string tolower [HTTP::uri]] starts_with \3 } {\n     pool \2\n  }\n}\n/g'

The one-liner above should convert the existing classes into iRules.

Instead of putting the classes into file and to "cat" you can try as well a tmsh command to list all classes:

tmsh list ltm httpclass | tr -d "\r\n" | sed -r "s/(\})/\1\n/g" | \
sed -r -e 's/^[[:blank:]]+//g' -e 's/\}$/ }/g' | tr -s '[[:blank:]]' | \
sed -r 's/^profile httpclass ([^ ]+) \{ defaults from httpclass pool ([^ ]+) paths regex ([^ ]+) \}/ltm rule rule_\1 {\n  if { [string tolower [HTTP::uri]] starts_with \3 } {\n     pool \2\n  }\n}\n/g'

Output can be merged into running configuration.

Thanks, Stephan
