How to select pool based on http payload ...

Hello, I follow the following reasoning, trying to avoid regex for example. Of course the code is very simple and needs validation source page, size of request, if there is content, etc. But I think this code is a start for you.

Regards.

when HTTP_REQUEST {
    if { ([HTTP::method] eq "POST") } {
        HTTP::collect [HTTP::header Content-Length]
    }
}

when HTTP_REQUEST_DATA {
    set decoded [decode_uri [HTTP::payload]]
    log local0. "=== Decoded $decoded"

    set ini [string first "\"idTerminal\"" $decoded]
    if { $ini != -1 } {
        set end [string first "," $decoded $ini]
        set value [string range $decoded $ini [expr {$end-1}]]
        set idTerminal [lindex [split $value ":"] 1]

        switch -exact $idTerminal {
            678 -
            679 {
                pool terminal_67x_pool
            }
            default {
                pool default_pool
            }
        }
    }
}
