NimbostratusURL and IP check iRule
Hi all i have the following code:
when CLIENT_ACCEPTED {
set poolDefault [LB::server pool]
}
when HTTP_REQUEST {
set path [string tolower [HTTP::path]]
if { $path contains "/g2b"} {
po...
when HTTP_REQUEST { switch -glob [HTTP::path] { "*/g2b*" { pool G2B_Pool } "*/portal/g2c*" { pool G2C_Pool } "*/_layout/15*" { if { [IP::client_addr] matches_glob "10.10.10.1\[01\]" } { pool G2B_Pool } } } }I removed the CLIENT_ACCEPTED code because, unless poolDefault is actually utilized elsewhere. I also removed the default branch (the else clause in the original code). If the pool associated with the Virtual Server is already set to B2B_Pool, then the default branch is redundant. Finally, I removed the string tolower for the path. Whether it makes sense depends on the path semantics for the webserver. See the Analysis section in this recipe for more details:

EmployeeThat's the reason for omitting the default branch: if a Request Target matches none of the conditions, then the default pool will automatically be used.
For the newest addition:
when HTTP_REQUEST {
switch -glob [HTTP::path] {
"*/g2b*" { pool G2B_Pool }
"*/portal/g2c*" { pool G2C_Pool }
"*/_layout/15*" {
switch [IP::client_addr] {
"10.10.10.10" -
"10.10.10.11" { pool G2B_Pool }
"10.10.10.61" -
"10.10.10.63" { pool G2C_Pool }
}
}
}
}
Moayad_Hamdan_3the ip address which i want to check is a response server ip address not the client.
after load balancer redirect the traffic to pool1 or pool2 , member servers of these two pools which are sharepoint servers are returning a url request to loadbalancer /_layout/15
load balancer will not redirect the traffic to correct pool , he will direct it to default pool because he can't detect \g2b or \g2c path.
i was thinking to make load balancer check the requester server ip and direct the traffic to correct pool.
i need load balancer to check both url and ip as all sharepoint servers in both pools will return the same url , load balancer should check the ip as well to direct the traffic correctly..
