How can i make apache limit requests to a certain url within a certain time frame?

I'm trying to use mod_evasive and mod_rewrite to accomplish this. With the configurations below apache just blocks all access to those URI's regardless of how many times a visitor accesses them within a given time frame.

So far i have create a map.db file like so:

touch /var/lock/apache2/map.db
chown www-data:www-data /var/lock/apache2/map.db
chmod 644 /var/lock/apache2/map.db

My apache2.conf contains this:

<Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

And my .htaccess file looks like this:

Options -Indexes
RewriteEngine On
RewriteCond %{REMOTE_ADDR} !^127\.0\.0\.1$
RewriteCond %{REQUEST_URI} ^/newthread.php$(\?.*)? [OR]
RewriteCond %{REQUEST_URI} ^/newreply.php(\?.*)?$
RewriteCond %{TIME_SEC},%{REMOTE_ADDR}:%{TIME_SEC}/180 ^(.*)\.(.*)$
RewriteMap dbm /var/lock/apache2/map.db
RewriteCond ${dbm:$2|$0} >1
RewriteRule .* /limit.html [L,R=302]
RewriteRule .* - [E=dbm:$2:$0]

<IfModule mod_expires.c>  
    # Turn on the module.
    ExpiresActive on
    # Set the default expiry times.
    ExpiresDefault "access plus 2 days"
    ExpiresByType image/jpg "access plus 1 day"
    ExpiresByType image/svg+xml "access 1 day"
    ExpiresByType image/gif "access plus 1 day"
    ExpiresByType image/jpeg "access plus 1 day"
    ExpiresByType image/png "access plus 1 day"
    ExpiresByType text/css "access plus 1 day"
    ExpiresByType text/javascript "access plus 1 day"
    ExpiresByType application/javascript "access plus 1 day"
    ExpiresByType application/x-shockwave-flash "access plus 1 day"
    ExpiresByType image/ico "access plus 1 day"
    ExpiresByType image/x-icon "access plus 1 day"
</IfModule>

The config you've posted would result in a 500 Internal Server Error since the `RewriteMap` directive is not permitted in `.htaccess`. Please confirm. However, the mod_rewrite directives that follow `RewriteMap` don't make sense (there is no `$2` backreference in the rules you've posted). But the preceding _conditions_ don't make much sense either? Please describe in natural language what it is you are trying to do (and how). What does map.db contain, how is this maintained/populated (by mod_evasive)? How are you overriding mod_evasive's (default?) behaviour to block the request?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
