I have configured one of the web-instance configuration files with the below snippet to allow redirects to work through another file without the need to restart the server. RewriteMap redirects txt:/mnt/var/www/html/abc/content/abc/na/ac/config_en_us/redirects/redirects.txtRewriteCond %{REQUEST_URI} ^(.*)$RewriteCond ${redirects:%1} >RewriteRule ^(.*)$ ${redirects:%1} [R=301,NC,L]When trying to restart the httpd after putting the code snippet i am not able to start the apache. The same code is working on other servers. Also the file was created and i have validated the permission. below is the error statement Syntax error on line 69 of /etc/httpd/conf.d/abc.conf:  RewriteMap: file for map redirects not found:/mnt/var/www/html/abc/content/abc/na/ac/config_en_us/redirects/redirects.txtI was finally able to bring the server up but the fix was not correct. Here is what i did. I created the same file with the same name in a the path /etc/httpd/conf.d and then moved it to the required path, after which apache was able to find the file and did come up. Can anyone help me understand what happened. 
Apache restart failing as it is not able to find a file which is present
