Dear list,
I have this scenario:
Two virtual servers ( A and B ) share the same DocumentRoot,
due to the fact that every server needs some special "global" variables,
each is set up with its own Perl interpreter.
The first Request to the page mypage.epl determinates which server has
the "right" Enviroment.
Subsequent Request to the same document from the other server shows that
not even the variable is "gone", but also the Embperl-Request and
therefore udat, mdat and fdat.
To make clear what happens:
httpd.conf:
MaxServers 1
<VirtualHost 12.34.56:8080>
Servername A
PerlOptions +Parent
PerlSwitches -Mlib=/webserver/A/lib
PerlRequire /webserver/A/lib/startup.pl
Embperl_Appname A-app
Embperl_Options 270338
Embperl_Cookie_Name "A_cookie"
DocumentRoot /webservers/htdocs
</VirtualHost>
<VirtualHost 12.34.56:80>
Servername B
PerlOptions +Parent
PerlSwitches -Mlib=/webserver/B/lib
PerlRequire /webserver/B/lib/startup.pl
Embperl_Appname B-app
Embperl_Options 270338
Embperl_Cookie_Name "B_cookie"
DocumentRoot /webservers/htdocs
</VirtualHost>
startup.pl:
use Some::Modul;
our $GLOBAL;
$GLOBAL = { key1 => A | B };
mypage.epl:
<html><pre>
outerTEXT
[*
my $r = shift;
print OUT "TEST:\n";
print OUT Data::Dumper::Dumper( $::GLOBAL );
print OUT Data::Dumper::Dumper ( $r );
*]
<pre></html>
If I access mypage.epl through server A
http://A/mypage.epl, I got the following ( expected ) result:
outerTEXT
TEST:
$VAR1 = {
'key1' => A
};
$VAR1 = bless( {}, 'Embperl::Req' );
If I call http://B/mypage.epl, I get :
outerTEXT
Not even the static "TEST" ist printed, neither the expected "key1 => B"
Attempts to set $udat{'somekey} fail because "Can't call method "init"
on unblessed reference at
/usr/lib/perl5/site_perl/5.8.5/Apache/SessionX.pm" and in fact is $self
in SessionX.pm undef.
Attemps to access $r->app fail, because of "Can't call method "app" on
an undefined value".
If I force a recompile of the page and access it at first from server B
everything is the other way round.
I expected each virtual host to have a global variable called $::GLOBAL
and %udat and $r to behave "normal" because, the not only have their own
Perlinterpreters but also different Embperl_Appnames and even the cookie
name ist different, so that their should be IMHO no interference.
What am I missing here?
Any hint is welcome.
thanks in advance
frank
