Nimbostratusuneven load with Universal persist profile
I created a universal persistence profile called X-FORWARDED-FOR and am using a very simple irule to persist on the x-forwarded-for header:
ltm persistence universal X-FORWARDED-FOR {

Nimbostratuswell I think things are looking better now that I increased the of requests I threw at it. Had to make a change:
got error HTTP::header in rule X-FORWARDED-FOR) requires an associated FASTHTTP profile on the virtual server
changed rule to:
when HTTP_REQUEST {
set xff [HTTP::header "x-forwarded-for"]
persist uie [HTTP::header "x-forwarded-for"]
log local0. "[IP::client_addr]:[TCP::client_port]: XFF: $xff"
}
when SERVER_CONNECTED {
log local0. "[IP::client_addr]:[TCP::client_port]: persist record: [persist lookup uie $xff]"
log local0. "[IP::client_addr]:[TCP::client_port]: Connected: [IP::server_addr]:[TCP::server_port]"
}
so here are the results varying the IPs equally:
40290:18
40310:14
40320:13
40330:16
here ar the results if the XFFs are all from similar subnets:
40290:14
40310:15
40320:16
40330:14
Think this was just a case of me not testing thoroughly enough... This load distribution looks great to me. Thanks for the help.
