Best grails implementation for tracking number of views (or unique visitors) for a web page?

I need to implement a very popular feature : displaying the number of views for a profile page.

For instance,开发者_如何学Python my profile page in StackOverflow will display how many persons have viewed my profile (just under my reputation score).

I suppose that the algorithm is based on some cookies and/or visitor IP addresses. Is there a simple way (a plugin or some code source) to implement it in Grails running on tomcat/apache?

Check out the Clickstream plugin: http://grails.org/plugin/clickstream

I haven't used it directly but it's based on a library that I've used outside of Grails. We considered using the plugin for a project and I reviewed the implementation and it looked solid, but I ended up leaving the project.

This doesn't directly address your request but you could query the table that it creates, or borrow the logic that it uses to do a specialized implementation for tracking individual pages.

Why don't you use Google Analytics?
