Yes, you can do that provided the logic is correct

when HTTP_REQUEST {
    log local0. "BI request received" 
    if { [HTTP::path] equals "/index.html" || [HTTP::path] equals "/benefits" || [HTTP::path] equals "analytics" || [HTTP::path] equals "/bicomposer" } {
        log local0. "BI request for BI service received. Selecting end server" 
        pool OHS_BI_9797 
        log local0. "BI end server selected: [IP::server_addr]"
    } elseif { [HTTP::path] equals "xxx" } {
        pool XXXXX
    }
}

Hey Kunjan

Can you see any error in this code ?

when HTTP_REQUEST {

switch -glob [HTTP::uri] {

"/index.html" -
"/benefits/*" -
"/analytics/*" -
"/xmlpserver/*" -
"/ui" -
"/mapviewer/*" -
"/bicomposer" -
"/bisearch/*" -
"/console/*" -
"/biacm/*" -
"/bimiddleware/*" -
 {

 / URI b URI

pool URI_b_pool
}
default {

 non-/site a URI

pool URI_default_pool
}
}
}

It would be easy to read if you can format (select the irule and Ctrl+K) this irule, Divya.

Hi Divya,

Have you tried the irule provided by Kunjan?

no jinshu, i had googled and saw people suggesting to use 'switch' instead . in this below url:-

https://devcentral.f5.com/s/feed/0D51T00006i7R59SAE

So i felt, this one is more efficient for my scenario.I will give the other code also a try and see. But if possible do let me know what could be wrong in this.

Hi Divya,

You have added options after "/bimiddleware/*" which doesnt required. Try below modified irule.

when HTTP_REQUEST {
    switch -glob [HTTP::uri] {
        "/index.html" -
        "/benefits/*" -
        "/analytics/*" -
        "/xmlpserver/*" -
        "/ui*" -
        "/mapviewer/*" -
        "/bicomposer*" -
        "/bisearch/*" -
        "/console/*" -
        "/biacm/*" -
        "/bimiddleware/*" { 

            / URI b URI
            pool URI_b_pool
        }
    default {
         non-/site a URI
        pool URI_default_pool
    }
}
}

Thank you jinshu ...switch statement wasnt working as was required , so tried with if elseif, its working. I have one more question, can i under http request event , check if the server port is 7777 and uri is something specific and then redirect accordingly ?

Hi Divya,

Glad that this got worked finally.

You can use [TCP:local_port] syntax for port based conditions.
