Internal REDIRECT : $r->is_initial_req() false but $r->main() undef

Hi again,

Subrequests are giving me a hard time :) I managed to use is_initial_req()
in my PATH_INFO subrequests, thanks to your previous answer. But I ran into
another subrequest : internal REDIRECT. My problem was that the subrequest
gets a ResponseHandler call, this time, so I need to have it access the
session perl variable used by the main request (I can't tie two variables to
the same Apache::Session::File file because I'm trying to use Transactional
mode).

Initially, I thought that I would be able to use $r->main() to get the main
request and access $r->main()->pnotes() to get my value. But $r->main()
returns undef even though $r->is_initial_req() returns 0 :-(

Sequence :

[Fixup] /perl/script1.pl
[Response] /perl/script1.pl /// prints  Location: /perl/script2.pl\n\n and
returns Apache2::Const::REDIRECT
-- no [CleanUp] for /perl/script1.pl here
[Fixup] /perl/script2.pl  //// $r->is_initial_req() returns 0 and $r->main()
returns undef

According to the
documentation<http://perl.apache.org/docs/2.0/api/Apache2/RequestRec.html#C_main_>,
this shouldn't happen, right?

Is there another way to access the main request ?
Is there another way to share perl variables between a request and its
subrequests ?


Thanks for your time,
