AdminHere's my crack, though I don't have a box currently to test on. I'm sure the and/or logic can be reduced, I'm curious if that would make the rule more processor efficient?
Unless jpg or gif would be anywhere else in your URL, I'd suggest using contains instead of ends_with. In the event a trailing / is appended in the uri, the rule wouldn't match. I added logging that you can use strictly while working on your rules.
rule Image_Rule {
when HTTP_REQUEST
{
if ( [HTTP::host} equals "www.mydomain.com" ) {
if ( [HTTP::uri] contains "jpg" ) {
use pool Image_Svr_80
log "JPG file requested by [IP::client_addr]"
}
elseif ( [HTTP::uri] contains "gif" ) {
use pool Image_Svr_80
log "GIF file requested by [IP::client_addr]"
}
else {
use pool Main_Svr_80
log "Default LB Method for [IP::client_addr]"
}
}
