AJAX rewrite rule for directories - ajax

Question

I'm trying to write a rewrite rule in addition to wordpress's :
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
I would not like everything to redirect to the main page. I have multiple sub-directories which need to be redirected too : http://www.example.com/sub1 and http://www.example.com/sub2. I'm doing this so my content can be loaded via Ajax.
I thought this would simply be
RewriteRule ^/(sub1|sub2)/(.*)$ http://www.example.com/$1/ [L]
Which I placed in the block here:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/(sub1|sub2)/(.*)$ http://www.example.com/$1/ [L]
RewriteRule . /index.php [L]
</IfModule>
Perhaps with wordpress you must use wp_rewrite_rule? I figured I could mess with the .htaccess file, get my rule to work, then move it over to functions.
any help would be appreciated.
Thanks.
UPDATE:
I've also tried to set the .htacces file back to the wordpress default... and add this code to the functions.php file for my child theme:
function AJAX_rewrite_rule() {
add_rewrite_rule(
'^/(sub1|sub2)/(.*)$',
'http://www.example.com/$1',
'top' );
};
add_action( 'init', 'AJAX_rewrite_rule' );
Seems to slow the load of everything down, but all files not found are still redirected to the main page, not the subdirectory.
UPDATE #2
I think I was going the wrong direction, as add_rewrite_rule is only to add a rule to the structure already put in place by wordpress. This all works by interpreting URL's, and changing them to variables for a DB query run by index.
I'm pretty sure I need to use $wp_rewrite->non_wp_rules. If anyone has more of an idea, let me know.

Try this, you seem to have ine bad line there:
<IfModule mod_rewrite.c>
RewriteEngine On
# RewriteBase /
# RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f #Means DONT redirect if file exists.
RewriteCond %{REQUEST_FILENAME} !-d #Means DONT redirect if directory exists.
RewriteCond %{REQUEST_URI} !^/sub1/
RewriteCond %{REQUEST_URI} !^/sub2/
# RewriteRule ^/(sub1|sub2)/(.*)$ http://www.example.com/$1/ [L]
RewriteRule . /index.php [L]
</IfModule>
What happens is, every time you add a "RewriteRule" all the "RewriteCond" are applied to that rule, and then you start with a blank slate:
RewriteCond A
RewriteCond B
RewriteCond C
RewriteRule Whatever [L] #This applies A, B, and C
RewriteRule Another [L] #This applies no rules
Perhaps that will help.
Also, you may try adding your "RewriteRule ^/(sub1|sub2)/(.*)$ http://www.example.com/$1/ [L]" right after "RewriteEngine On" if that doesn't work…
