I'm trying to write out html code or javascript code fragments to show
the progress of the operations.

Re the first issue, I only have experience of ns_connchan but I
believe the situation is the same.
You can specify r,w,e, or x for the *argument* ?when? upon creation of
the callback, but the callback will be triggered upon timeout with a
*value* of $when = "t" regardless of what you specify as the argument
when setting up the callback.
"The optional argument /when/ can consist of one or more characters of
r, w, e, or x, specifying, when the callback should fire. "
Re the binary problem, What is it you are writing to the channel?

Hi!
We have some long running scripts, e.g. shrinking of large PDF
files, and want to prevent reverse proxy and browser timeouts.
To achieve this, we are trying to periodically send small packages
from the server to the browser while these scripts are running.
First we tried with ns_conn and ns_sockcallback
set mychan [ns_conn channel]
ns_sockcallback $mychan noop t 1
proc noop {handle when} {
# do something
}
ns_chan close $mychan
When we call this, we get the following error:
error invalid when specification "t": should be one/more of r,
w, e, or x
which contradicts the documentation of the command here:
https://naviserver.sourceforge.io/n/naviserver/files/ns_sockcallback.html
<https://naviserver.sourceforge.io/n/naviserver/files/ns_sockcallback.html>
Then we tried something similiar with ns_connchan
set mychan [ns_connchan detach]
ns_connchan callback -timeout 1 $mychan noop "r"
but a ns_connchan write $mychan throws the following error:
ns_connchan: only binary channels are currently supported.
Channel conn0 is not binary
Is there a solution to this problem?
regards,
Wolfgang
