Prevent executing .htaccess of parent folder - apache

Question

I have two different sites on same domain for example:
First site in the root directory http://example.com/
Second site in subfolder http://example.com/site2/
Each site have his own .htaccess
When i enter to second site (http://example.com/site2/), in log of mod_rewrite i see that apache trying to execute .htaccess of first site (http://example.com/).
So, the question is how to prevent this?
Thanks

Answer 1

http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriteoptions
inherit
This forces the current configuration to inherit the configuration of
the parent. In per-virtual-server context, this means that the maps,
conditions and rules of the main server are inherited. In
per-directory context this means that conditions and rules of the
parent directory's .htaccess configuration are inherited.
Rules inherited from the parent scope are applied after rules specified in the child scope.

While you can not stop the execution of the .htaccess in http://example.com
You CAN place another .htaccess in http://example.com/site2/ and any rule created here that overrides the rules in the .htaccess of the parent folder will be executed here but not in the parent folder.
For example, I recently had a case where I was rewriting any non-www version of my main site, which we'll call example.com to its www equivalent: www.example.com
The problem this caused is anyone going to my second site, which we'll call site2.com would actually redirect the user to www.example.com/site2.com/ even if the user enters site2.com OR www.site2.com OR http://www.site2.com in their browser's address input
What I had to do to fix it is makes changes in 2 .htaccess files, first in the root http://www.example.com then in a separate .htaccess located in http://www.example.com/site2.com/
1) http://www.example.com .htaccess:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
2) http://www.site2.com (http://www.example.com/site2.com/) .htaccess(this also forces the www version of site2.com):
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.site2\.com$ [NC]
RewriteRule ^(.*)$ http://www.site2.com/$1 [R=301,L]
RewriteCond %{HTTP_HOST} ^site2\.example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.example\.com/site2\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.site2\.example\.com$
RewriteRule ^/?$ "http\:\/\/www\.site2\.com\/" [R=301,L]
Feel free to rip apart my regex, I am by no means a regex master. I also realize that this can creates 2 or maybe more extra redirects but this is the only way I could get this to work, without reassigning my DocumentRoot through through the host...which is probably a better option if your host can do it, mine would/could not...
