We tested siwapp application, which is an opensource invoicing application, but we had some problems, the error log was full of these:
[Sat Mar 30 17:32:55 2013] [error] [client xx.xx.xx.xx] File does not exist: /home/invoice/web/invoices
The site seemed to work fine otherwise.
It seemed that there was a problem with the app's .htaccess.
The main problem was here:
RewriteCond %{REQUEST_URI} \..+$
which matches all files with a dot in the filename, but the rule was ment to match files that start with a dot.
The fix for this is:
RewriteCond %{REQUEST_URI} /\..+$
After that fix, the app created errors because of a request for favicon.ico.
Well, the fix for that is simple enough
RewriteRule .+/favicon.ico$ favicon.ico [L]
So the whole .htaccess looks like this:
Options +FollowSymLinks +ExecCGI -MultiViews
AddDefaultCharset utf-8
Order deny,allow
Deny from all
Order deny,allow
Deny from all
RewriteEngine On
# Rule to test if rewrite module is available during
# the install process
RewriteRule test_rewrite1\.txt test_rewrite2.txt
RewriteRule .+/favicon.ico$ favicon.ico [L]
# uncomment the following line, if you are having trouble
# getting no_script_name to work
#RewriteBase /
# we skip all files with .something
RewriteCond %{REQUEST_URI} /\..+$
RewriteCond %{REQUEST_URI} !\.html$
RewriteRule .* - [L]
# we check if the .html version is here (caching)
RewriteRule ^$ index.html [QSA]
RewriteRule ^([^.]+)$ $1.html [QSA]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
# no, so we redirect to our front web controller
RewriteRule (.*) index.php [L,QSA]
