title: set default http header request to empty in tcl http
body: <p>I would like to set the default http hrader in Tcl http package to empty and then selecetively put some header on my own using a dictionary. I need to do this becasue I see many items (like sock, binary, -binary, -strict, queryoffset etc) in my Tcl http request header which are not present in the header specified by other web browser like firefox. I get correct response in broswer so I want exactly those heater which are send by the brower. For this I need to set the default http header in Tcl http package to empty, and mannually set the headers (which I can do). How do I empty the default headers?</p>
