As we all know, whether or not dynamic pages with .php/.asp/.cgi extensions are treated the same as plain .html files by the spidering search engines is a matter of constant debate.
I've recently discovered a very handy method of forcing your server to treat .php files as if they were .html by adding the following line to an .htaccess file:
AddType application/x-httpd-php .php .html
The result is that you can create .html files with embeded PHP scripts and they are parsed in exactly the same way.
What I want to know is will a spidering engine such as Google or Inktomi be able to differenciate between a normal .html page and one that has been through the PHP interpreter. Both appear as plain HTML in the browser, but will this affect spidering?
FYI - none of these pages will have variable=value pairs passed in the URLs such as index.html?prod=23.
