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"
