I just added Co-op to my website. My site is all in PHP appart from the main (front) page which was in plain html. Originally I wasnt going to put ads onthe front page, but in order for co-op to see all of the adds I have on my site I had to configure the co-op control panel to say www.mydomain.com rather than www.mydomain.com/page1.php Now to do this I had to change the main (front) page to php. Not a big deal, but now it is called index.php not index.html. Is it bad practice to call the file index.php and not have an index.html file, or should I create a file called index.html and point it to index.php
The index.php file is ok, the server recognizes it as you default homepage to show. In fact both are ok the server identifies both of them as your default home page so you should use what suits you.
Don't forward your index.html to index.php.... just name your file index.php like cornchild said. Redirecting/reloading pages may confuse visitors.
