With the old hunchentoot I was able to get the flexi-stream of the request using (content-stream request) and then when my ajax handler wanted to update the upload progress it would read (flexi-stream-position of the stream that I kept in a session). With the new hunchentoot this doesn't work. I realize that (content-stream request) is not a flexi-stream, so when I save a stream in my session I make a flexi-stream using (make-flexi-stream (hunchentoot::content-stream request) :external-format hunchentoot::+latin-1+). Then when ajax handler reads flexi-stream-position of the saved stream I always get 0. What am I missing? Thank you, Andrei
