Hi Edi,

Also busy here, but I have seen some odd recent behaviour with
Hunchentoot and mod_lisp behind Apache 2. In keep-alive scenarios, the
second request stalls for 60 seconds; I'm not sure whether the request
is satisfied at that point, or whether the connection is simply
closed. Perhaps this problem shares a common root with the upload
problem?

As a workaround, I've been setting a Connection: close header on all
requests, hoping to get the problem solved later on. It does the
trick, though of course it's not a long-term solution. In case anyone
needs it, here's my workaround:

(defun mod-lisp-close-hack (req)
  (prog1 nil
    (setf (slot-value req 'headers-in)
	  (cons '(:connection . "close")
		(remove :connection (slot-value req 'headers-in)
			:key #'car)))))

(setq *dispatch-table* (cons #'mod-lisp-close-hack
			     *dispatch-table*))


I'll try to debug this and the upload issue if I can.
