    Hi Sulabh Srivastana,

    Remove use command.

    when HTTP_REQUEST {
	if { [HTTP::uri] starts_with "/core" } {
		pool Pool_X
	} elseif { [HTTP::uri] starts_with "/service" } {
		pool Pool_X
	} elseif { [HTTP::uri] starts_with "/ims" } {
		pool Pool_X1
	} elseif { [HTTP::uri] starts_with "/portal" } {
		pool Pool_Y
	} elseif { [HTTP::uri] starts_with "/ords" } {
		pool Pool_Z
	}
}

    switch version:

    when HTTP_REQUEST {
	switch -glob [HTTP::uri] {
		"/core*" -
		"/service*" { pool Pool_X }
		"/ims*" { pool Pool_X1 }
		"/portal*" { pool Pool_Y }
		"/ords*" { pool Pool_Z }
	}
}

    without using pool:

    when HTTP_REQUEST {
	switch -glob [HTTP::uri] {
		"/core*" -
		"/service*" { node 1.2.3.4 10004 }
		"/ims*" { node 1.2.3.4 10009 }
		"/portal*" { node 5.6.7.8 10006 }
		"/ords*" { node 9.10.11.12 10008 }
	}
}

Hi,

when HTTP_REQUEST {
	log local0. "requri0: [HTTP::uri] - cip: [IP::client_addr]"
	if { [HTTP::uri] starts_with "/core" } {
		log local0. "requri1: [HTTP::uri] - cip: [IP::client_addr]"
		pool Pool_X
	} elseif { [HTTP::uri] starts_with "/service" } {
		log local0. "requri2: [HTTP::uri] - cip: [IP::client_addr]"
		pool Pool_X
	} elseif { [HTTP::uri] starts_with "/ims" } {
		log local0. "requri3: [HTTP::uri] - cip: [IP::client_addr]"
		pool Pool_X1
	} elseif { [HTTP::uri] starts_with "/portal" } {
		log local0. "requri4: [HTTP::uri] - cip: [IP::client_addr]"
		pool Pool_Y
	} elseif { [HTTP::uri] starts_with "/ords" } {
		log local0. "requri5: [HTTP::uri] - cip: [IP::client_addr]"
		pool Pool_Z
	}
}

Can you investigate the logs on cli and pool stats on gui?

tailf /var/log/ltm | grep requri
