NimbostratusLoad Balance and persistence
Can load balance and persistence co-existed in F5 where requests are coming from proxy servers?
So far I had tried these:
1:
- 'enable' the "Insert Xforward For"
- Set pool as round robin
- Set persistence as "destination address" or "source address"
- inserted this irule:
when HTTP_REQUEST {
persist uie [HTTP::header "X-FORWARDED-FOR"]
}
Result 1:
- Sticky persistence OK
- Not Load balancing. All requests go to one Web server
2:
- DISable the "Insert Xforward For"
- Set pool as round robin
- Set persistence as "destination address" or "source address"
- inserted this irule:
when HTTP_REQUEST {
persist uie [HTTP::header "X-FORWARDED-FOR"]
}
Result 2:
- Sticky persistence NOT working.
- Load balancing OK
If answer is yes, appreciate you could provide references.
Thank you.
Jonathan_Chong_Load balance based on client's IP would be good for us based on the irule below:
when HTTP_REQUEST {
persist uie [HTTP::header "X-FORWARDED-FOR"]
}
However, subsequent request does not persist on the same Web server which causes session sticky problem after few minutes. I had session time out set on Universal persistence to 45 minutes.
- I had also set Tcp idle time to higher value (default 300 seconds) but it stil does not persist.
Any clue why?
Thanks in advance.
