Apache::ASP and Apache request object

[Dmitry Beransky <db...@ucsd.edu>]

Hi,

Joshua, I guess this question is for you.

Some time ago I asked how to combine ASP's session management and 
Apache::Session.  You recommended I use Script_OnStart to set $Session to 
an instance of Apache::Session.

In order to get an instance of Apache::Session, I need to get to the 
current session id which is stored in a request header, which means I need 
to get a reference to the current apache request object.  I've browsed 
through Apache::ASP code and docs and realized that there is no documented 
API for accessing the underlying request, but I can still do it by 
accessing the internal structures directly:

    $sessionID = $self->{'asp'}->{'r'}->header_in('sessionID');

So my question is: how reliable this method is?  Can I assume that the 
structure of the ASP and GlobalASA will not change in the future?

Thanks
Dmitry

You can get the current request like Apache->header_in('sessionID')
So this doesn't rely on ASP internals, you'll be fine.
