    Append 

    ?[HTTP::query]
    to your redirect destination (sample below). The only problem with this approach is that you will always be redirected to a location with ?-symbol at the end, whether you have any query parameters in the original request or not.

    HTTP::respond 302 Location "https://webname.com/bbb/default.aspx?[HTTP::query]"

    If the above bothers you, you can write a condition to determine if the question mark should be appended or not as follows

     Determine if original request contains query parameters
if { [HTTP::query] ne "" }{
  set myQuery "?[HTTP::query]"
} else {
  set myQuery ""
}
 your condition goes here
HTTP::respond 302 Location "https://webname.com/bbb/default.aspx$myQuery"
