Link Controller iRule commands

just found this reference for v9.x at ask f5

 

 

http://support.f5.com/kb/en-us/products/lc_9_x/manuals/product/bigip9_2_2lc/BIG-IP_9_2_2LC_Guide-18-1.htmlwp1191322

 

 

which uses this example:

 

 

 

when CLIENT_ACCEPTED {

 

set uri [HTTP::uri]

 

if { $uri ends_with ".gif" } {

 

pool my_pool

 

} elseif { $uri ends_with ".jpg" } {

 

pool your_pool

 

}

 

}

 

 

and use layer 7 (http uri) information in the conditional IF statement. So it seems that you can use layer 7 information, contained in tcp data, as long as you define this "allowed" events in the iRule:

 

 

 

CLIENT_ACCEPTED

 

CLIENT_DATA

 

LB_SELECTED

 

LB_FAILED

 

SERVER_CONNECTED

 

SERVER_DATA

 

RULE_INIT

 

CLIENT_CLOSED

 

SERVER_CLOSED

 

 

The v11 Config guide uses only CLIENT_ACCEPTED and SERVER_CONNECTED examples. One of those is this one querying TCP information in order to evaluate traffic and take the proper decision:

 

 

when CLIENT_ACCEPTED {

 

if { TCP::port equals 80 } {

 

node 10.1.2.200 80

 

}

 

}

 

 

Even tough is not clear and well defined the scope of iRules for the LC , I think the information above should back up my intention of redirect traffic based on IP addresses.

 

 

My bad no to look this information first on ASK f5.
