iRule for directing traffic from a specific host and URI to a given pool

use this irule.

                when HTTP_REQUEST {
                    if { [string tolower [HTTP::uri]] starts_with "/uri1*" } {
                         pool pool_X
                             }      
                     }

Hi, Samir. This appers to be a straight URI redirect to a pool. I am looking to also match the source of the request to a specific host, host1.internet.com. Thank you for your help. Vadim.

try this...

when HTTP_REQUEST {
  if { [string tolower [HTTP::host]] equals "host1.internet.com" } {
    if { [string tolower [HTTP::uri]] starts_with "/uri1" } {
      pool pool_X
    } 
  }     
}

Hi,

if you are using version 11.4 or above, you can configure Local traffic policy instead of irule.

• Policy
  • require http
  • controls forwarding
• Rule 1 :
  • Condition
    • http-host host equals host1.internet.com
    • http-uri path starts_with /uri1
  • Action forward pool Pool_X

Arpydays, Entered your rule, and it passed F5 mustard. Will test in the morning but certainly makes sense and should work. Thank you very much.

Stanislas, I am running a BigIP version 10.2.4. Thank you as well.

Vadim.

Hi,

in the irule, create a else statement with default pool assignment. if there is no default pool assignment, and the user browse first to /uri1 then to /uri2 in the same TCP connection, the second request will be assigned to the previous pool.

When CLIENT_ACCEPTED {
    set default_pool [LB::server pool]
}

when HTTP_REQUEST {
  if { [string tolower [HTTP::host]] equals "host1.internet.com" } {
    if { [string tolower [HTTP::uri]] starts_with "/uri1" } {
      pool pool_X
    } else { pool $default_pool}
  }     
}
