HTTP Trace method and Query

Should the first line of trace echo the query string or not ?
Or is it up to container (web server ?)

WAS, TOMCAT, WLS all return trace without the query string
so if you browse

http://localhost/path?query

server responds with:

TRACE http://localhost/path HTTP/1.1

But I have seen containers returning

TRACE http://localhost/path?query HTTP/1.1


Any ideas why someone does not want to echo query ?
