I may have started you on the proverbial wild goose chase with this
cookie stuff, so let's start over.
There are two main differences between a page sent to the browser via
ns_returnredirect vs one sent by ns_respond. ns_returnredirect puts
together a small HTML page and sends it off to the browser with
content type text/html, using the header data that's already in the
conn data structure. ns_respond takes the set of headers passed to
it, replaces the headers in conn with the ones that are passed in,
and then sends the string off to the browser. So the two significant
differences are the handling of the headers, and that
ns_returnredirect sends a properly formed HTML page whereas my use of
ns_respond sends only the word "Redirect". My hunch is that the
former is the problem.
So could there be something about the way the -headers argument to
ns_respond is handled that is somehow garbling the data? Could Tcl
be doing something to it as it's being passed along?

Janine,
Now I'm getting confused. If the browser or the telnet sends the
cookie it
just received, the outputheaders on test2.tcl don't include a set-

header. So it isn't in the outputheaders I guess. I just did this:

My browser shows the same behavior as telnet. OACS isn't filling the
outputheader with the set-cookie if the browser/client has a cookie.

Well no, I'm not sure that it sends the Set-Cookie header on every
request. But something about the change I made is causing OACS to
act as though the browser has cookies turned off, so I kind of zeroed
in on that. If there are other things that could cause that symptom
I should look at those too, I just didn't know what they might be.

Janine,
I would try the second request via telnet, but send the cookie
value you
received on the first request. Are you sure that OACS sends the Set-

already
there?

So Set-Cookie is there.
However, if I request test.tcl in the browser, I get redirected to
test2.tcl which prints out the output of ad/ns_conn headers and ad/
ns_conn outputheaders, where there is nary a Set-Cookie in sight.
Somehow it's getting lost along the way.
I'm perplexed.

It is only necessary to use the Host: header if you use virtual
hosting.

However if I request test.tcl in the browser I do get properly

Yes, I have printed out the contents of outputheaders and the
Set-

If you telnet into the page, what do you get sent back?
I'm not sure where in here you add the Set-Cookie header? Do you
know that it
is in the output headers at the time you grab a copy of the set?

This should be simple, but it's turning out not to be.
First I used this code, which I got from a post at openacs.org
(and
the poster got it from the AOLserver docs for ns_respond):
set headers [ns_set new myheaders]
ns_set put $headers location $url
ns_respond -status $return_code -type text/plain -string
Redirect -
headers $headers
This worked as far as the redirect and status code are
concerned, but
cookies were no longer functioning.
I noticed that ad_set_cookie (an openacs proc) adds a key
called
Set-
Cookie to the "ns_conn outputheaders" set, so I tried this,
hoping to
capture all possible relevant values:
set headers [ad_conn headers]
set outputheaders [ad_conn outputheaders]
set allheaders [ns_set merge $headers $outputheaders]
ns_set idelkey $allheaders location
ns_set put $allheaders location $url
ns_respond -status $return_code -type text/plain -string
Redirect -
headers $allheaders
No improvement; cookies still don't work. BTW, I tried it
with
both
ns_conn and ad_conn but they both give the exact same
output, so
same
end result.
Any suggestions on what I might be doing wrong here?
I know that the best way to fix this would be to create an
ns_returnmoved function in AOLserver, but I was trying to avoid
having any of our clients using a customized version.
Thanks for any suggestions,
