# This program generates Apache Rewrite rules based on the source and destination sites provided to the function. It works with internal as well as external redirects.

# RewriteRule ^/source-path$ https://destination-url-for-external-redirect.html [R=301,NC,L]
# RewriteRule ^/source-path$ /destination-path-for-internal-redirect.html [R=301,NC,L]
# Example : Redirect www.abbott.com/news to www.abbott.com/newsroom.html
