Setup F5 big-ip irules to allow source ip to specific uri only and drop other access

I would like to know how to setup a irule to meet below requirement:

  1. if source ip equal to '1.2.3.4'
  2. allow access to "https://abc/def" only (abc is virtual server, def is data group mapping content on virtual server)
  3. and block other access, not allow to access to "https://abc/XXX" (XXX for others mappings)

 

thank you.

    Hello Doi.

    Try this ->

    when HTTP_REQUEST {
	# reject user if source IP is not 1.2.3.4 and first path value is not included in DATAGROUP
	if { ([class match [getfield [string tolower [HTTP::path]] "/" 0] neq DATAGROUP]) || ([IP::addr [IP::client_addr] neq 1.2.3.4]) } {
		reject
	}
}

    Regards,

    Dario.
