I had a bit of a hard time getting Zend Framework to run on my 1&1 hosting. It was all down to the .htaccess file in the end. The default htaccess configuration in the ZF getting started guide just doesn’t work, and neither did all the other posts I could fine on the subject around the internet, however, I’ve finally cracked it.
Presuming you’ve put your ZF index file in the webroot, here’s what the 1and1 htaccess file should look like.
AddHandler x-mapp-php5 .php
AddType x-mapp-php5 .php
Options -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule !\.(txt|swf|js|ico|gif|jpg|png|css|xml)$ /
Note: The same file will not work on my local dev machine, which is running only PHP5. You will need to comment out the first two lines (AddHandler, AddType) to get it to run on a stadard PHP5 installation.
