PHP 4 to 5 Upgrade Issue

I need to compare PHP 4 code with PHP 5 interpreter on same machine. I am following the examples in Adam Trachtenberg's Upgrading to PHP 5 (O'Reilly 2004) listed in "Appendix C: Installing PHP 5 Alongside PHP 4" with regard to using virtual hosting and relative ports on Apache httpd. I have also read the Apache docs online regarding virtual hosting. And I cannot get it to work. I have the following relevant entries in Apache httpd.conf: Listen 8181 Listen 80 <VirtualHost *:80> LoadModule php4_module modules/libphp4.so DocumentRoot /srv/www/htdocs </VirtualHost> <VirtualHost *:8181> DocumentRoot /srv/www/htdocs ScriptAlias /* /srv/www/htdocs <Directory /usr/local/php-5.0.4/bin> </Directory> </VirtualHost> When I browse http://localhost:8181/ I always get the root (/index.html) instead of the alias (/php5/index.php). Any clues? tia, ~mark ******************************************************************************************************************** This email and any file transmitted with it may be confidential and is intended solely for the use of the individual or entity to whom it is addressed..
