Redirect host and path but keep query string on redirect

There's a problem with this, it will redirect to: https://new-domain.com/my-account/web-contact-response.aspx? if there is no query.

Here's what I do:

when HTTP_REQUEST {

if { [string tolower [HTTP::path]] equals "/selfserv/webcontactresponse.aspx" } {

if { [HTTP::query] ne "" }{

HTTP::redirect "https://new-domain.com/my-account/web-contact-response.aspx?[HTTP::query]"

else {

HTTP::redirect "https://new-domain.com/my-account/web-contact-response.aspx"

}

}

I came to this thread wondering if the performance was the same to do:

when HTTP_REQUEST {

if { [string tolower [HTTP::uri]] equals "/selfserv/webcontactresponse.aspx" } {

HTTP::redirect "https://new-domain.com/my-account/web-contact-response.aspx"

elseif { [string tolower [HTTP::path]] equals "/selfserv/webcontactresponse.aspx" } {

HTTP::redirect "https://new-domain.com/my-account/web-contact-response.aspx?[HTTP::query]"

}

}
