Hi all!

I've just read this articles:
http://developer.yahoo.com/performance/rules.html
http://yuiblog.com/blog/2007/04/11/performance-research-part-4/

It might be interresting to make some changes to Wicket to better handle
some rules..

For example, I was thinking of:

* "Add an Expires Header" -
http://developer.yahoo.com/performance/rules.html#expires
Wicket already set a short term expiration for bundled JS, CSS, images
resources. We could get better caching performance by using ressources names
with versions and than using long term caching..
The drawback is an updated resource must have its name changes..
At least it would be nice to overide this expiration

* "Move Scripts to the Bottom" -
http://developer.yahoo.com/performance/rules.html#js_bottom
Handling this in IHeaderResponse implementation?

* "Configure ETags" -
http://developer.yahoo.com/performance/rules.html#etags
Plugging this with page cache?

* "Maximizing Parallel Downloads"
By using some automatic round-robin absolutes URL for resources
downloading.. It would means more configuration for setting absolute URL
pool for each resources types (CSS, images, JavaScript..)
