    If you want redirect to "https://test123/?abcd=xyz/1234/notfound.aspx"

    when HTTP_REQUEST {
	set path [string trimleft [HTTP::path] "/"]
}
 
when HTTP_RESPONSE {
	if { [HTTP::status] == 404} {
		HTTP::redirect "http://test123/?abcd=$path"
	}
}

    If you want redirect to "https://test123/?abcd=xyz"

    when HTTP_REQUEST {
	set val [getfield [HTTP::path] / 2]
}
 
when HTTP_RESPONSE {
	if { [HTTP::status] == 404} {
		HTTP::redirect "http://test123/?abcd=$val"
	}
}

    If you want redirect to "https://test123/?abcd=fdfbglskbvksdfbvlk"

    when HTTP_REQUEST {
	set val [URI::query [HTTP::uri] item]
}
 
when HTTP_RESPONSE {
	if { [HTTP::status] == 404} {
		HTTP::redirect "http://test123/?abcd=$val"
	}
}
