重定向到维护页面...如何选择页面

so i've manage to redirect all urls to a specific page for maintenance. That works ok. My problem is that i don't want all urls to go to maintenance... just two..

How do i redirect when a user click the following url's (including subfolder,etc...):

http://www.mysite.com/discography/
http://www.mysite.com/songbook/

this is my code that works ok (i've allowed my localhost ip address and the ip address on my live site to bypass the rules):

RewriteCond %{REMOTE_ADDR} !^99\.999\.99\.999
RewriteCond %{REMOTE_ADDR} !^0\.0\.0\.0
RewriteCond %{REQUEST_URI} !/maintenance.php$ [NC]
RewriteRule .* /maintenance.php [R=307,L]

Simply adjust the RewriteCond that matches the URI accordingly:

RewriteCond %{REQUEST_URI} ^/(discography|songbook)/ [NC]
