Subject Re: Problem with RequestRec and Headers
Date Mon, 24 Sep 2007 08:47:23 GMT
Yep, that's a bug

perldoc Apache2::RequestUtil

  # get the global request object (requires PerlOptions +GlobalRequest)
  $r = Apache2::RequestUtil->request;

which means u need GlobalRequest in apache config, which I'm not a big fan
of. Better raise a bug in cpan rt for this module and get Tatsuhiko to fix
it. By the looks of it, this hasn't been updated in a while.

personally I don't really see a need for Apache::Singleton::Process unless
there needs to be a module for consistency in Apache:: namespace,
class::singleton does pretty much the same job. If you need a per-request
singleton meanwhile,  cookup something quickly of your own that uses apache
pnotes to store the instance

perldoc Apache2::RequestRec
