HTTP reverse proxy irule help

Hi Joseph,

you may use the iRule below as a starting point...

when CLIENT_ACCEPTED {
     Store the default pool name 
    set default_pool [LB::server pool]
    set orig_hostname "www.abc.com"
    set orig_base_uri "/en-gb/jobs"
    set new_hostname "www.xyz.com"
    set new_base_uri "/en-gb"

}
when HTTP_REQUEST {
    if { [string tolower [HTTP::path]] starts_with $orig_base_uri } then {
        HTTP::header replace Host $new_hostname
        if { [set dest [lindex [RESOLV::lookup @208.67.222.222 -a [HTTP::host]] 0]] ne "" } then {
            node $dest
            set rewrite_enabled 1
        } else {
            HTTP::redirect "/dns-error.html"
            set rewrite_enabled 0
        }
    } else {
        pool $default_pool
        set rewrite_enabled 0
    }
    STREAM::disable
}

when HTTP_RESPONSE {
    if { $rewrite_enabled } then {
        if { [set location [HTTP::header value "Location"]] ne "" } then {
            HTTP::header replace "Location" [string map [list $orig_hostname $new_hostname $orig_base_uri $new_base_uri] $location]
        }
        STREAM::expression "@$orig_hostname@$new_hostname@@$orig_base_uri@$new_base_uri@"
        STREAM::enable
    }
}

Note: I've streamlined some parts of the original iRule and also remove some parts which may cause trouble.

Note: Make sure to use a ONECONNECT profile on your Virtual Server to switch the

[node]

[pool]
