I have stripped everything out of my .htaccess but this one line:
ErrorDocument 404 /errorDocs/notfound.html
notfound.html is my custom 404 page.
In running tests:
"http://www.mysite.com/nopage.html" brings up the custom 404 page.
"http://www.mysite.com/nopage.php" brings up 1&1's default 404 page.
"http://www.mysite.com/index.htm" brings up a "Multiple Choices" error, as does any URL with any extension if the same filename.php exists.
Surprisingly (probably only to me), a URL containing a file with a similar extension, like "http://www.mysite.com/about.pp" causes the rewrite of the URL to "http://www.mysite.com/about.php".
Can anyone explain what I've done wrong ?
I apologize if this is such a beginner question. After 2 days of troubleshooting, I'm throwing in the towel. I need some direction on the most efficient way for an htaccess dummy to learn what he needs to handle custom 404 pages (and canonicalization) without going to a 4 year college on htaccess.
