How to set cookies with yaws

Question

Is there function like php setcookie . If not then how?

EDITED:

yaws_api:setcookie("lang","lang_value", "/"),
yaws_api:find_cookie_val("lang", (A#arg.headers)#headers.cookie),

find_cookie_val returns empty string because setcookie didnt set coockie.

Answer 1

Finally i did it through http header:

out(A) ->
% read 
  yaws_api:find_cookie_val("lang", (A#arg.headers)#headers.cookie),

% send to browser 
  [{header,["Set-Cookie:","lang=ruler;","expires="++to_cookie_expire(60*60*24*30)++";"]},
  {html, ...}]
end.

to_cookie_expire(SecondsToLive) -> 
  Seconds = calendar:datetime_to_gregorian_seconds(calendar:local_time()),
  DateTime = calendar:gregorian_seconds_to_datetime(Seconds +
  SecondsToLive), httpd_util:rfc1123_date(DateTime).
