Porblem with my session_id and zope
|
|
Hi all,
I was having a lot of trouble with the bySession candidacy function
lately when no matter what I did values I set for the identifier seemed
to be getting ignored.
this was the relevant section in my http.conf (solaris box)
<Directory />
Options FollowSymLinks
AllowOverride None
Backhand byAge 5
Backhand removeSelf
Backhand byRandom
Backhand bySession mcid=
</Directory>
but when I set the cookie mcid to a session_id it made no difference
and all requests went to
random box's (linux boxes) each time and ignored the sessions
the apache servers that the requests are being sent to are inturn proxying
the requests to
a zope server on a different port number and its on the zope server that
the cookies are being set
RESPONSE.setCookie("mcid", "ac110a12")
I needed to find out what was wrong so I kicked off gdb to see what was
going on and noticed
that the value of the session_id being retrieved from the http header was
inclosed in quotes see below
The version of backhand I have I got from
:pserver:anonymous [at] commedia:/storage/cvs
about a week ago.
Breakpoint 2, bySession (r=0xf95d0, servers=0xffbee590, n=0xffbeed94,
identifier=0xdbab8 "mcid=\"") at builtins.c:351
351 const char *session_id=NULL, *cookie;
(gdb) s
355 if(!identifier)
(gdb) n
363 if(cookie = ap_table_get(r->headers_in, "Cookie")) {
(gdb)
364 if(session_id = strstr(cookie, identifier))
(gdb)
366 session_id += strlen(identifier);
(gdb) p session_id
$1 = 0xf6138 "mcid=\"ac110a41\""
(gdb) n
368 if(!session_id && r->args) {
(gdb) p session_id
$2 = 0xf613e "\"ac110a41\""
Which meant that the decode loop was getting a " as the first character to
decode as a hex digit and it
all went wronge from there
This means I can get the session_id to work if I replace the bySession
configuration in my http.conf with
Backhand bySession mcid="
I have three questions
Does this mean that the zope web server sets cookies different to the rest
of the web servers in the world?
Should this be addressed in the code for bySession?
The README.bySession file talks about a ap_log_error statement that can be
uncommented for debugging, where is it?
Thanks in advance,
Derek
