Apache htaccess mod rewrite - php

Question

So, I am having some issues with my htacces file trying to do some re-write conditions.
What I am trying to do is:
There are multiple domains pointed to this web folder.
If the domain is anything but example.com I want it to rewrite to example.com
UNLESS - the path is /path
Everything is working now except when you go to www.otherexample.com/path
It is hitting the last rule and changing the url to http://dev.otherexample.com/index.php?qs-rewrite=path and causes a redirect loop.
Here's the entire htaccess file
DirectoryIndex index.php
<IfModule mod_rewrite.c>
RewriteEngine On
#RewriteBase /
RewriteCond %{HTTP_HOST} !example\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/path [NC]
RewriteRule ^.*$ http://dev.example.com%{REQUEST_URI} [L,R=301]
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . %1/%2 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ index.php?qs-rewrite=$0&%{QUERY_STRING} [L]
</IfModule>

Answer 1

This should be your complete .htaccess:
DirectoryIndex index.php
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} !example\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/path [NC]
RewriteCond %{QUERY_STRING} !qs-rewrite=[^&]+ [NC]
RewriteRule ^ http://dev.example.com%{REQUEST_URI} [L,R=301,NE]
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . /%1/%2 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ /index.php?qs-rewrite=%{REQUEST_URI} [L,QSA]
</IfModule>
