Haproxy conditions

Since I keep forgetting them I've put them here.

To form a condition, you can use the following syntax after the rule that it applies to:

<HAProxy action statement> if|unless [!]acl1 <AND|OR|or|'||'> [!]acl2 ...

• if - the condition is TRUE if the result of the ACLs is TRUE.

cat <<EOL >> /etc/haproxy/haproxy.cfg
