irule only working intermittently

I wonder if it's a simple tcp connection/http request issue. A bigip is connection orientated so multiple http requests on the same tcp connection might not be delivered to the right pool if you're doing this selection in an irule.

See Using an iRule to load balance HTTP requests to multiple pools

I'd try a oneconnect profile on the virtual server.

Hope this helps,

its not a live vip so only I would be connecting?

what is a oneconnect profile?

is there a better irule I could use to achieve this?

when we visit the site https://xyz.site.co.uk the majority of the time it doesnt work until two or three refreshes.

have you tried http analyzer tool or tcpdump?

Hi,

Probably it's too basic but maybe worth asking - is this vip terminating SSL or working as proxy SSL?

any other suggestions for a better rule then please :)?

the vip has the ssl profile but it forwards onto http internal connections.
