Try this:

when HTTP_REQUEST {
    if { [HTTP::header exists X-Forwarded-Host] } {
        HTTP::header replace Host [string trim [lindex [split [HTTP::header X-Forwarded-Host] ","] 0]]
    }
}

This of course assumes that X-Forwarded-Host contains 2 host names separated by a comma, versus two separate X-Forwarded-Host headers (which might also be possible).
