(installation troubles) PHP4 & Apache under Windows 2000

I have installed PHP4 under Windows 2k, and I have a few problems. The .php pages load successfully, however, I to see some piece of headers make their way into the browser, and this only with PHP enabled pages. For instance : X-Powered-By: PHP/4.0.0 Expires: Mon, 26 Jul 1997 05:00:00 GMT Last-Modified: Mon, 26 Jun 2000 13:45:02 GMT Cache-Control: no-cache, must-revalidate Pragma: no-cache Content-type: text/html When the PHP script tries to set up a cookie, here is what I have : X-Powered-By: PHP/4.0.0 Expires: Mon, 26 Jul 1997 05:00:00 GMT Last-Modified: Mon, 26 Jun 2000 13:46:44 GMT Cache-Control: no-cache, must-revalidate Pragma: no-cache Set-Cookie: VW_WEBCENTER__USER=admin Set-Cookie: VW_WEBCENTER__STATUS=7 Location: index.php Content-type: text/html And this seems to prevent cookie creation too... I don't have this problem under IIS, with the same installation of PHP. I don't have this problem with regular html pages under Apache either. J'ai bien un expose_php = Off dans le php.ini. Any idea of where this comes from? Thibault Dangréaux
