I would like to redirect www.hostname.com/some path/?cpao=12 to www.hostname.com/some path/?kmas=12.
Essentially replacing the word cpao with kmas and keeping everything else the same.
Any help will be appreciated.
Enable mod_rewrite and .htaccess through httpd.conf and then put this code in your .htaccess under DOCUMENT_ROOT directory:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} ^cpao=([^&]*) [NC]
RewriteRule ^ %{REQUEST_URI}?kmas=%1 [R,L]
RewriteRule ^hostname.com/somepath/\?cpao([0-9]+)$ hostname.com/somepath/\?kmas=$1
you use regex in htaccess $1 is the numbers that was catched in group 1
