404 cannot be found

Hello,

I have an iRule that checks the source IP Subnet and if it matches what's in the data group it make the connection with a different pool other than the default pool, otherwise the connection goes like normal to the default pool.

What's happening now is that when the IP matches what's the data group, I am getting 404 page cannot be found.

any help with this is greatly appreciated.

when HTTP_REQUEST {
    if { [class match [IP::client_addr] equals datagroup_name] } {
        pool someother_pool
    }
}
