Another solution could be to use Apache mod_setenvif and mod_headers to conditionally set cache headers.
SetEnvIf Request_URI "^/current$" OVERRIDE_CACHE_HEADERS=TRUE
Header set Cache-Control no-cache env=OVERRIDE_CACHE_HEADERS
I have not tried this specific configuration, but I have a similar one that sets environment variable with a RewriteRule directive and then uses Header to conditionally change Cache-Control directives
You want all content inside some directory to have a different expire than the rest of the site--not just a few files. For example: Dynamically generated JS files; frequently changing logo and other images files; or often edited CSS that you want very short cache lifetimes for..
Apache is directly serving up that content--it's not a view folder or something for a framework which PHP is including out of.
You have the mod_expires module enabled
.htaccess files are searched for in every directory along the way to the file being served up if they're enabled starting at the docroot. Therefore, the easiest would be to put a new .htaccess file in the directory for which you wish to change the expire limit. If your site is www.foo.com and you want /current to have a different expire header a simple .htaccess file in www.foo.com/current. The file just needs:
# enable expirations with mod_expires
<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 2 weeks"
</IfModule>
This being said... a block in your httpd.conf file(s) for the entire server, a virtual host block, or in the docroot's .htaccess would be more elegant and manageable solutions.

Use could use
<Location>apache directive to define different options (e.g. expire) for specific URL.I'm assuming:

A useful example that should integrate well with rewrites:
