Configuration Woes

Hello, I'm a well seasoned developer dipping my toe into PHP/Apache/MySQL. I installed Mozilla FireFox Version 0.9.3 and PHP4.3.8 and Apache 1.3.31 running in Windows 2000 Version 5 SP 4. I appended the following lines to httpd.conf ScriptAlias /php4/ "E:/Programs/PHP4.3.8/" AddType application/x-httpd-php4 .php4 .phtml .php Action application/x-httpd-php4 "php.exe" I created a small test file named test.php which contains the single line of code: <?php echo '<p>Hello World</p>'; ?> I navigate to http://127.0.0.1/ and I get the default apache page. I navigate to http://127.0.0.1/test.php and get the following error message Bad Request Your browser sent a request that this server could not understand. Invalid URI in request GET /test.php HTTP/1.1 ---------------------------------------------------------------------------- ---- Apache/1.3.31 Can someone please help me troubleshoot this problem. Thank you Jim Bailey
