PHP and Apache Authentication

Hi All, I am trying to protect portions of my website. I am using pache 2.x and php4.X. I don't want to use apache authentication within the Directory directive because I can't utilize sessions if I do that. So I want to use PHP to authenticate from a postgresql database. This works fine on the pages I have put it on, the problem is I want it on all pages in a given directory but I don't want to edit every page in that directory. Is there a way to configure apache to include something in every response? Example: http://test/v1/v1.php v1.php: ... include(../auth.inc) ... This file is protected. http://test/v1/v1-test.php v1-test.php doesn't contain the include above, but I still want to protect it. Thanks Glenn
