[Building Sakai] How to redirect everything through a Filter

[Stephen Marquard]

Hi Joshua,

If you want to see response time per request, you can enable debug logging in the RequestFilter to do this. It will log the start and end of each http request with elapsed time.

You can also enable some logging in Tomcat's server.xml config file, and if you're using apache as a front-end, you can enable time-to-first-byte reporting in the log format.

Regards
Stephen

I'd like to install a filter to intercept all incoming requests, to be
able to measure response times and performance. I have installed a
filter and it loads, but no requests are sent to it.

    <filter-mapping>
        <filter-name>LogFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

With the above filter-mapping, the filter never gets any requests sent
through it. I assume this is because of the way Sakai already handles
filter-mapping and servlet-mapping.

Anyone have an idea how a filter can be installed into Sakai to
receive all requests first?
