I'm stuck at trying to redirect all urls in specific path to lower case – CentOS

Im able to get all my urls to redirect to lower case using the following in my conf file

RewriteEngine On
RewriteMap  lc int:tolower
RewriteCond %{REQUEST_URI} [A-Z]
RewriteRule (.*) ${lc:$1} [R=301,L]

works like a charm…

The issue is though, I really need this to apply only to URLs www.example.com/this-doesnt-change/Random_Random_111

or www.example.com/this-doesnt-change/Random/Random_111

or even www.example.com/this-doesnt-change/Random

Basically anything after www.example.com/this-doesnt-change/

I’ve tried replacing

RewriteCond %{REQUEST_URI} [A-Z]

with

RewriteCond %{REQUEST_URI} this-doesnt-change/.+

but all I get is "too many redirects" error

Or should I be restricting the rule to this path using a function of the conf file?

Any insight is appreciated

EDIT:

the .htaccess file

##

#
# The line 'Options +FollowSymLinks' may cause problems with some server configurations.
# It is required for the use of mod_rewrite, but it may have already been set by your 
# server administrator in a way that disallows changing it in this .htaccess file.
# If using it causes your site to produce an error, comment it out (add # to the

# they work, then it has been set by your server administrator and you do not need to 
# set it here.
