NimbostratusYou could try an iRule with a Datagroup to match on a " HTTP host Header + Path" and map it to select a pool.
Note: I haven't tested this,
when CLIENT_ACCEPTED {
set DEFAULT_POOL [LB::server pool]
}
when HTTP_REQUEST {
set HOST_PATH_2_POOL [string tolower [getfield [HTTP::host] ]][string tolower [URI::path [HTTP::uri] 1 1]]
set POOL_SELECT_VALUE [class lookup $HOST_PATH_2_POOL HOST_and_PATH_2_POOL_DG]
if {$POOL_SELECT_VALUE eq ""} {
set POOL_SELECT_VALUE [class lookup [string tolower [getfield [HTTP::host] "." 1]] HOST_and_PATH_2_POOL_DG]
}
#log local0.notice "HOST_PATH_2_POOL = $HOST_PATH_2_POOL"
#log local0.notice "POOL_SELECT_VALUE = $POOL_SELECT_VALUE"
if {$POOL_SELECT_VALUE eq ""} {
set USE_POOL $DEFAULT_POOL
} else {
set USE_POOL $POOL_SELECT_VALUE
}
}Your DG would look like:
NimbostratusI will try your suggestion tomorrow...
With limited success, I had started down a a path using a similar code with a DG using only "/appname" and used a "hammer" approach with a first irule before it like this:
Irule #1
when HTTP_REQUEST {
if { [HTTP::uri] eq "" || [HTTP::uri] eq "/" } {
HTTP::redirect "http://commonserver.domain.name/" "
event disable all
}
}
Irule#2
when HTTP_REQUEST {
#Check to see if the DataGroup matches a URI call
set svr_port [class match -value -- [HTTP::uri] starts_with port_fwd_applications]
#Check to see if a LB decision has already been made for this connection
if { [LB::server addr] != "" }{
#Check to see the LB port matches the DataGroup entry
if {[LB::server port] != $svr_port } {
#If the port and DataGroup dont match, remove the serverside connection and re-load-balance
LB::detach
}
}
if {$svr_port eq ""}{
#DataGroup doesn't match the URI, drop the connection
#or do something else here
drop
}
}
when LB_SELECTED {
#A new LB decision has been made, check to see if the DataGroup has fired
if {$svr_port != ""}{
#The DataGroup URI matches, check to see if the ports match
if {[LB::server port] != $svr_port } {
#Send the traffic to the DataGroup Port
LB::reselect node [LB::server addr] $svr_port
}
}
}
