JSF: Speeding up delivery of JSF pages to the client/browser using http compression and a caching filter

Howdy folks, well I thought I would share / combine a few of the techniques I found a month or two ago that I now use to speed up the delivery of JSF pages to the client. Leveraging caching of images/css and javascript objects and enabling HTTP 1.1 compression...A thanks goes out to Jean-Francois Arcand, lowec and Rafael Pereyra

Products involved:

The steps involved:

Thats all, doing so I was able to gain much faster client/server responses and improve the overall user experience.

The only issue I have experienced doing so, was that every now and again I had to clean out my browser cache when I was testing a modified page.

June 25th 2008 Update

Since using the above technique to speed up delivery I noticed that there were a few issues with the "back" button in Internet Explorer and Safari browsers. I have now gone down the path of intoducing a phace listener in to the JSF framework; making sure that each page is not cached so that the page will be refreshed by the system. The phase listener was I found courtesy of http://turbomanage.wordpress.com/2006/08/08/disable-browser-caching-in-jsf/. I have updated the phase listener presented here slightly to introduce another meta tag, "EXPIRES" I set this to current date minus a year to make sure the systemrefreshes the content.

The performance gain I was getting chaching pages hasn't actually hindered that much as all. When woodstock 4.2 was released, many performance improvements were seen, for more information see: http://www.nabble.com/Woodstock-4.2-Performance-tc15884700.html

• GlassFish v2ur2
• NetBeans 6.1
• Visual JSF: 1.1.1

Try out both ideas, se which one works better for you, let me know what you think.

Cheerio!
