Re: Session identity vanishing

Did you try to set *use-remote-addr-for-sessions* and/or *use-user-agent-for-sessions* to NIL? Cheers, Edi.

Another session problem
by Nicolas Neuss 08 Apr '15

08 Apr '15

Hello, I have the following problem. Hunchentoot 1.2.26/SBCL 1.0.57 is serving pages from behind Apache. More precisely, my Apache config is <VirtualHost *:80> ServerAdmin neuss(a)scipolis.de ServerName yyy.math.fau.de ServerAlias yyy.math.fau.de DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log ErrorDocument 404 /index.html ProxyRequests Off ProxyPass /wissen http://localhost:8002 ProxyPassReverse /wissen http://localhost:8002 </VirtualHost> Now when accessing the page <http://yyy.math.fau.de/wissen/admin-login?nr=4> for the first time (!), the "form" gets an additional "action" parameter which is an absolute path like <form method=post action='/admin-login?nr=4&hunchentoot-session=17997%3A98C123D51D88E2BDBD28DC2E00D16E42'> while "href"s are (correctly) relative like <a href='about?hunchentoot-session=17997%3A98C123D51D88E2BDBD28DC2E00D16E42'>Informationen</a> This leads to a wrong redirection when submitting the form. Is this a bug or is anything wrong with my setup? I'm using Hunchentoot 1.2.26 from Quicklisp. Thank you, Nicolas P.S.: If one refreshes the page after first access the action parameter goes away and everything works as desired. Also with redirecting to the login page I can remove this behaviour, but I would like to understand what is going on here.

hunchentoot serving manifest files, ie. .appcache files.

how to serve manifest files, ie. .appcache files wit hunchentoot? (mime-type #p"path/to/anifest/file") >nil nil is there a way to do? or is it jsut enough to proxy with apache or nginx front and configure those to serve manifest files, as it is noted in w3schools html5- appcache topic? before i try myself, just asked to bring it to attention for possible renewing improvements to the hunchentoot.

Re: A bug in functon parse-content-type.
by Jingtaqo Xu 08 Apr '15

Hi Hans, The whole thing I want is a a stable hunchentoot server which will be compatible with other web clients and a stable drakma client which will be be compatible with other web servers,whether the web clients/servers follows http protocols well or not should not be the reason which makes hunchentoot/drakma failed directly. I hope you can understand that if drakma/hunchentoot failed directly, my commercial business will fail too. I must say that the codes from Edi has very high qulities,and I have high respect to Edi and you for that. For the case of this question, I hope chunga/drakma/hunchentoot could accept a special feature or a speical variable to make them accept the content type header which not follows http protocols well,like cl-http does. ----------------------------------------------------------------------------- (parse-mime-content-type-header "application/x-www-form-urlencoded; text/html; charset=UTF-8") ==> (:APPLICATION :X-WWW-FORM-URLENCODED :CHARSET :UTF-8) ----------------------------------------------------------------------------- I think your solution(request-with-bad-content-type) will be a little trivial for me. If you accept my suggestion, I can give you a patch for these three packages(chunga/drakma/hunchentoot).

Hello Hans, my setup is common lisp implementation: SBCL 1.1.14 Linux 3.10.5 i686 and Linux 3.10 amd64 Hunchentoot version 1.2.24 This code can help you to reproduce the problem: (ql:quickload "hunchentoot") (defvar *acceptor* nil "El acceptor de hunchentoot") (defun inicia-ht (&optional (port 4242)) (format t "Iniciando el servidor en el puerto ~5,'0d~%" port) (setf *acceptor* (make-instance 'hunchentoot:easy-ssl-acceptor :port port :ssl-certificate-file "./server.crt" :ssl-privatekey-file "./server.key")) ; (setf *acceptor* (make-instance 'hunchentoot:easy-acceptor ; :port port) (setf (hunchentoot:acceptor-document-root *acceptor*) (pathname "/var/www/")) (hunchentoot:start *acceptor*)) (inicia-ht) You can test with ab with and without ssl ab -n 1000 -c 10 https://localhost:4242/index.html ab -n 1000 -c 10 http://localhost:4242/index.html

hi i cannot sustain a session. i login to my app. it shows my login name as i programmed. when i refresh the page it stays there. but when i refresh for the second time my session name and other things goes away and instead i see what is there for the not loginned case. I think i miss something in hunchentoot session hadling. ;all html generated by a macro: (defmacro ff (tag) `(defun ,tag (&rest c) (with-output-to-string (*standard-output*) (format t "<~a ~{~a='~a' ~}> ~{~a ~}</~a>" ',tag (car c) (cdr c) ',tag)))) ;;defining all tag functions: (progn (ff html) (ff title) (ff head) (ff meta) (ff link) (ff style) (ff script) (ff body) (ff span) (ff div) (ff section) (ff p) (ff form) (ff input) (ff button) (ff textarea) (ff a) (ff h1) (ff h2) (ff h3) (ff h4) (ff h5) (ff h6) (ff ol) (ff ul) (ff li)) ;authentication utilities used by the home page function at the bottom: (defun signed-in-p () (if (and (boundp '*session*) (session-value '*signed-in *session*)) t nil)) (defun signed-up-p (x y) (if (with-connection *conn1spec* (query (:select 'username 'password :from 'users.users :where (:and (:= 'username x) (:= 'password y))))) t nil)) (defun sign-in () (let ((username (parameter "username")) (password (parameter "password"))) (if (signed-up-p username password) (progn (start-session) (setf (session-value '*username) username) (setf (session-value '*signed-in) t) (morph-status-plate (session-value '*username))) (with-output-to-string (s) (princ (morph-sign-in-form) s) (princ "No record found!" s) (princ (a (list :href "/form-sign-up") "Sign up") s) )))) ;the data base querying functions are working correctly ;views generated: (defun morph-write-button () (div (list :style "border:1px solid; float:left;") (a (list :href "/writingp") "write"))) (defun morph-status-plate (username) (div (list :id "status-plate" :style "border:1px solid; float:left;") (span () "123 users online") (span () username) (button (list :onclick "ajaxlogout()") "logout"))) (defun morph-sign-in-form () (div (list :id "sign-in-form" :style "border:1px solid; float:left;") (form (list :method "" :action "") (input (list :id "username" :type "input" :name "username")) (input (list :id "password" :type "input" :name "password")) (input (list :onClick "ajaxsignin()" :type "button" :value "login"))))) ;at last ;the page i generate as home page: (div (list :id "sign-in-form-or-status-plate" :style "height: 45px; border: 1px solid; float:left;") (if (signed-in-p);;;;;; (with-output-to-string (s) (start-session) (princ (morph-status-plate (session-value '*username)) s) (princ (morph-write-button) s)) (with-output-to-string (s) (princ (morph-sign-in-form) s) (princ (a (list :href "form-sign-up") "Sign up") s))))

I have another question about hunchentoot. Is it possible to use server sent events with hunchentoot, like other html5 improvements mentioned in w3schools-html5 such as app cache, local storage, session storage? as that one related to and depend on the server side support.

ssl support
by José Ronquillo 08 Apr '15

08 Apr '15

I am currently writing a web application using Hunchentoot; but it seems that there is a problem with its ssl support (using easy-ssl-acceptor): for some unknow reason for me, sbcl, the commom lisp implementation that I use, grows its memory whitout limit when I make tests with ab. I have tested with hunchentoot:easy-acceptor and this problem with the memory does not occur. Does anyone of you guys had seen this behavior?
