Sessions inconsistent
Hi
Sometimes I can retrieve data out of %udat, sometimes I can't. I tried adding domain and path environment variables to no avail.
PerlSetEnv EMBPERL_SESSION_CLASSES "MySQL Semaphore"
PerlSetEnv EMBPERL_SESSION_ARGS "DataSource=dbi:mysql:webdata UserName=mgmtsesh69"
PerlSetEnv EMBPERL_SESSION_DOMAIN .quicks.co.uk
PerlSetEnv EMBPERL_SESSION_PATH /
Regards
Steve

Yes
EMBPERL_SESSION_CLASSES
EMBPERL_SESSION_ARGS
EMBPERL_SESSION_HANDLER_CLASS
are global
EMBPERL_COOKIE_*
are _not_ global and can be set different in different contexts (By setting
a different cookie name you get a different session for different projects)

Are you saying that ALL of the EMBPERL_SESSION_[INSERT NAME HERE]
variables are global?

That's dangerous, because you can't have different values for these
configuration directives. They are global. (Yes that's something that should
be changed sometime, but it isn't yet). If you have different values the
session management get's initialized with the values from the first request,
so it's becomeing even worth if differnet childs have different first
requests and get differently initialized. (I guess that's what you are
seeing in conjuction with EmbperlObject)
Beside the fact that loading Embperl (as any other Perl module) is more
memory efficient, it save you a lot of problems. So just put that
PerlModule HTML::Embperl
in somewhere and set your session variables before.

I have finally managed to get session management working; I used to have
the EMBPERL_SESSION_CLASSES and EMBPERL_SESSION_ARGS in my </Location
sessionLocation> without using a PerlModule statement. I'd have
something like:
<Location somewhere>
PerlSetEnv blah
SetHandler perl-script
PerlHandler HTML::EmbperlObject
</Location>
WITHOUT a PerlModule HTML::Embperl statement anywhere in httpd.conf.
For some totally obscure reason (at least to me), HTML::Embperl(Object)
would randomly (well, there seems to be some order but I can't work it
out yet) decide to start session management or stop it...
<sigh>

You can load Embperl in three way (when using mod_perl)
1.) PerlModule HTML::Embperl
2.) in a startup file which is loaded via PerlRequire, you say use
HTML::Embperl
3.) you don't load it explicitly, the mod_perl does it on the first request
(not recommended, because it less efficient)
For 1., put the PerlSetEnv with the session vars, before the PerlModule
statment in your httpd.conf
For 2., put the PerlSetEnv with the session vars, before the PerlRequire
statment in your httpd.conf, or the $ENV setup in a BEGIN block before the
use
For 3. it doesn't matter where you setup the config, as long as it is
somewhere in your httpd.conf

Stupid question, but how do you make sure it's set BEFORE embperl is
loaded?

The config is ok. Make sure it is set before Embperl is loaded.
Do see something like "Embperl session management enabled" at server startup
?
