Passing Variables in a non-CGI LC Server?

[Mike Bonner]

Ok. The problem with "start session" is most likely trying to write the
session file to a place without write permissions.  Make sure you set the
sessionsavepath to a place you can write to.

Having said that.. I can't make it work.  I can get past start session, all
the way to stop session, no trouble, but the session variables aren't
populated on start session.  (this is with on-rev most recent installed
version of lc server I assume)
No errors, just.. doesn't work.  The session file is created, I can grab
the sessionid etc, but the session array isn't actually loaded.

I simplified as much as possible to try and figure out WHY it won't work
now. If anyone have ideas, i'd appreciate a pointer.

Heres the code...

<?lc
set the sessionSavePath to the defaultfolder -- saving session stuff to the
same dir as the .lc

start session
-- start the session. If you don't do this BEFORE your if check,
$_SESSION["counter"] will always be empty
if $_SESSION["counter"] is empty then
   put 1 into $_SESSION["counter"] -- give initial value if necessary
end if

put "Session counter=" & $_SESSION["counter"] & "<br>"

  add 1 to $_SESSION["counter"]
  put "Incrementing Session counter:" & $_SESSION["counter"]
-- increments and displays the future counter

stop session

?>


On each load, it should increment the current session. So the first hit it
should say 1, and 2 for the future. Then 2 and 3, 3 and 4 4 and 5...
As I said the sessionid file is created as expected (with 4 bytes in it)
but the counter value doesn't appear in the session variables upon start
using like it should.
