New HTTP Logger Grails plugin

I’ve wrote a new Grails plugin – httplogger. It logs: request information (url, headers, cookies, method, body), grails dispatch information (controller, action, parameters), response information (elapsed time and body). It is mostly useful for logging your REST traffic. Full HTTP web pages can be huge to log and generally waste your space. I suggest to map all of your REST controllers with the same path in UrlMappings, e.g. /rest/ and configure this plugin with this path. Here is some simple output just to give you a taste of it. 17:16:00,331 INFO filters.LogRawRequestInfoFilter - 17:16:00,340 INFO filters.LogRawRequestInfoFilter - 17:16:00,342 INFO filters.LogGrailsUrlsInfoFilter - 17:16:00,731 INFO filters.LogOutputResponseFilter - >> #1 returned 200, took 405 ms.17:16:00,745 INFO filters.LogOutputResponseFilter - >> #1 responded with '{count:0}' 17:18:55,799 INFO filters.LogRawRequestInfoFilter - 17:18:55,799 INFO filters.LogRawRequestInfoFilter - 17:18:55,800 INFO filters.LogRawRequestInfoFilter - 17:18:55,801 INFO filters.LogOutputResponseFilter - >> #2 returned 404, took 3 ms.17:18:55,802 INFO filters.LogOutputResponseFilter - >> #2 responded with '' Official plugin information can be found on Grails plugins website here: http://grails.org/plugins/httplogger or you can browse code on github: TouK/grails-httplogger.

It is mostly useful for logging your REST traffic. Full HTTP web pages can be huge to log and generally waste your space. I suggest to map all of your REST controllers with the same path in <span class="class">UrlMappings</span>, e.g. /rest/ and configure this plugin with this path.
