IRule Customization

We have a requirement to create irlue with the following logic

 

We have One VS and Two POOL (Pool x and Pool Y)and differentiate the traffic based on requested hostname by the following irule

 

==================

 

when HTTP_REQUEST { if {([HTTP::host] contains "auction.com")} {pool Auction-Pool}

 

if {([HTTP::host] contains "test.com") {pool test-Pool}

 

}

 

====================

 

For certain hostname (auction.com) we need to do the following

 

From internet: All users has to access : https://auction.com

 

From internet: All users should not have to access to: https://auction.com/test/admin

 

From intranet : Only following subnet below should have access to : https://auction.com/test/admin

 

Network1 Range: 10.10.10.X/24

 

Network2 Range: 20.20.20.X/24

    I think the following should work for you:

    when HTTP_REQUEST {
    set selectedPool [LB::server pool]
    set lowerHost [string tolower [HTTP::host]]
    set lowerPath [string tolower [HTTP::path]]

    if {$lowerHost ends_with "auction.com"} {
        set clientIP [getfield [IP::client_addr] "%" 1]
        if {($lowerPath starts_with "/test/admin") && !(([IP::addr $clientIP equals 10.10.10.0/24]) || ([IP::addr $clientIP equals 20.20.20.0/24]))} {
            reject
        }
        set selectedPool Auction-Pool

    } elseif {$lowerHost ends_with "test.com"} {
        set selectedPool test-Pool
    }
    pool $selectedPool
}

    I have also published as a snippet here Snippet: irule-customization-63561
