Limit concurrent requests

It is possible to limit the number of concurrent requests to a URL. You can implement this limitation by means of a filter.

See also the next example. It limits the number of concurrent requests to the path /application/a/ to 100, and those to the path /application/b/ to 50:

<filter>
    <filter-name>LimitRequest</filter-name>
    <filter-class>ch:nevis:navajo:apglue:httpd_${HTTPD_LIB_VERSION}_x:servlet:ApacheConfigFilter</filter-class>
    <filter-lib>@PKG_HOME@/webapp/WEB-INF/lib/libApache${HTTPD_LIB_VERSION}_Servlet.so.1</filter-lib>
    <init-param>
        <param-name>ServerConfig</param-name>
        <param-value>
            QS_LocRequestLimit '/application/a/' 100
            QS_LocRequestLimit '/application/b/' 50
        </param-value>
    </init-param>
</filter>

You can find the above example configuration in directory /opt/nevisproxy/examples/apache_module/ of the installed nevisProxy package.
