Improve apache perfomance

Here are some ideas in improving apache performance by adding some lines in a .htaccess file. I used this in a CakePHP project recently.

<IfModule mod_rewrite.c> #url rewrite used by cakephp
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>
IndexIgnore *
<IfModule mod_headers.c>
    # 1 YEAR
    <FilesMatch "\.(ico|pdf|flv)$">
    Header set Cache-Control "max-age=29030400, public"
    </FilesMatch>
    # 1 WEEK
    <FilesMatch "\.(jpg|jpeg|png|gif|swf)$">
    Header set Cache-Control "max-age=604800, public"
    </FilesMatch>
    # 2 DAYS
    <FilesMatch "\.(xml|txt|css|js)$">
    Header set Cache-Control "max-age=172800, proxy-revalidate"
    </FilesMatch>
</IfModule>
<IfModule mod_deflate.c>
        AddOutputFilterByType DEFLATE text/text text/plain text/css application/x-javascript application/javascript text/javascript
</IfModule>

The additional lines basically set some cache and compression (mod_deflate) headers for the static content.
