Loadbalance a URL to 3 URLs

you can use the RAND funtion in irule ,try below irule

when HTTP_REQUEST {
# Generate a random number between 1 and 3
set random_num [expr {int(rand() * 3) + 1}]
if {[string tolower [HTTP::path]] eq "/exampletext"} {
HTTP::redirect http://abc$random_num\ee.xyz.com/exampletext_$random_num
}
}

ASMAPMLTM you can use ragunath154 example but that will be random load balancing using the random function rather than round robin. Why do you have the requirement to load balance the host portion rather than allowing the use of 1 host and then load balancing to all servers that would handle request from the 3 seperate hosts?

Is this something related with Openshift service url. Because I'm getting confused when you say redirect. Do you want redirect or host header modify & send the traffic to your respective servers which handle each domains.

This worked, but dont sometimes it fails out of nowhere

when RULE_INIT {
set ::c 0
}
when HTTP_REQUEST {
event enable
switch $::c {
0 {
HTTP::redirect "https://abc1ee.xyz.com/exampletext_1"
incr ::c
event disable
}
1 {
HTTP::redirect "https://abc2ee.xyz.com/exampletext_2"
incr ::c
event disable
}
2 {
HTTP::redirect "https://abc3ee.xyz.com/exampletext_3"
set ::c 0
event disable
}
}
}
