Could be...
Perhaps it is so because there is a separate API call just for that
and it is more general:
Httpd_AddHeaders $socket $header $value
Well, it works perfectly when I let Httpd_ReturnData handle the status. I made the changes to lib/direct.tcl (see patch below). However, not thouroughly tested, thats why it worries me a little. It boils down to the question "why it raises an error in return codes other than 0 and 302 originally?"
My idea is to use Direct_Url's as callback handlers for AJAX async requests. These handlers use HTTP codes, especially 200/400 to evaluate the result...
