SSl Offloading Content Switching

Try this - https://devcentral.f5.com/wiki/iRules.http__uri.ashx

The sample irule should work for your use case, for example:

when HTTP_REQUEST {

Will this work with SSL offloading as the request will be HTTPS? Many thanks

Yes, just ensure you have a ssl client profile defined on the VIP to decrypt the data.

Great thanks for the help will give it a try. Thanks as you can tell I am complete F5 noob

You'd necessarily have to offload the SSL at the F5 with a client SSL profile, so yes.

Ok I have the above working with Pools, how would also add host URLs to this irule. I have two more URLS to get working which are running on servers which are already in my pools.

So if I have a node which is already in a pool that runs a forum for example so I want to redirect /forum/ to an individual server.

Many thanks Matt

At some point you may want to switch to a switch (pun intended) for an easier read. As for sending traffic to a specific node, you can use the node command directly, or a variation of the pool command if the node is a member of a pool:

when HTTP_REQUEST {
    switch -glob [string tolower [HTTP::uri]] {
        "/test1*" {
            pool pool1
        }
        "/test2*" {
            pool pool2
        }
        "/forum*" {
            pool pool1 member 10.80.0.1 80
            node 10.80.0.1 80
        }
    }
}

Great thank you I have switched to the switch and it is much cleaner I have allot or URLS to switch in our environment, my testing is working well.

Thanks Matt

Hi I am having problems with this now :-/. The AppOffline url works the web Forum and IRD does not. I am trying to cut over from two old cisco content switches. Also I want all other request to go to my default web pool is this possible?

when HTTP_REQUEST { switch -glob [string tolower [HTTP::uri]] { "/WebForum" { pool Main-WS-Pool member 192.168.10.211 80 } "/AppOffline" { pool IIS01-IISO2-Pool } "/IRD" { pool IIS01-IISO2-Pool } "/supplier_test_F" { pool IIS01-IISO2-Pool } "/DataCapture" { pool IIS01-IISO2-Pool } "/supplierG" { pool IIS01-IISO2-Pool } "/UAT*" { pool IIS01-IISO2-Pool member 192.168.10.11 80 }

Two things:

1. You're doing a [string tolower ] evaluation but the match URIs aren't lowercase. Not sure how the /AppOffline condition is working.

2. I would probably consider using wildcard matches for these URIs. (Ex. "/webforum*").

As for a default condition, simply use a "default" condition at the bottom of the switch.

switch x {
    "B" { do something }
    "C" { do something }        
    default { do something }
}
