Apache - Rewrite url without loop - mod-rewrite

Question

Well I say what's said in the title again, I can't find a way to rewrite all my urls without getting a loop.
I've tried many options but I can't find about one way which avoid a redirection loop:
RewriteRule ^/(.+) http://example.com/example/index.php$1 [R,L]
RewriteRule ^/?(.*) /var/www/example/index.php$1 [R]
RewriteRule ^/(.*)$ %{DOCUMENT_ROOT}/example/index.php$1 [R]
RewriteRule ^$ /example/ [L]
And below is my directory apache-conf
<Directory /var/www/example>
Options FollowSymLinks
DirectoryIndex index.php
Order allow,deny
Allow from all
</Directory>
I understand why it loops though I can't imagine (either find!) the good rule to do what I want.
EDIT
Basically I'm redirecting example.fr hosted at OVH to an IP virtual machine. Does this could get involved in my issue ?
Cheers

Answer 1

RewriteEngine On
RewriteCond %{REQUEST_URI} !^/example/
RewriteRule (.*) /example/index.php/$1 [L,R]
This will redirect anything that is outside /example/ to /example/index.php adding the original path in the end
EDIT:
So, if you want everything to be redirected to /project_name/index.php instead, you need to swap the word "example" both in RewriteCond and in RewriteRule lines with your project name...
PS:
The RewriteCond line here is needed to ensure the rewriting does not loop (hence the url stayed /example/contact when you tried this).

Answer 2

This rule should not cause a loop
RewriteRule ^/(.+) http://example.com/example/index.php$1 [R,L]
This rule will not do anything at all
RewriteRule ^/?(.*) /var/www/example/index.php$1 [R]
For this rule you should add a RewriteCond
RewriteCond %{REQUEST_URI} !^/example/
RewriteRule ^/(.*)$ %{DOCUMENT_ROOT}/example/index.php$1 [R]
This is fine
RewriteRule ^$ /example/ [L]
