[~rakesh.a] Thats the reason why I used a LinkedHashMap - I think the performance impact is not very high - even with a greater list of files.

> Implementation of org.apache.wicket.resource.CssUrlReplacer (if enabled), might affect performance, and increase the loading time of CSS files, if they contain many background-image properties with 'url()' values. 
> In one instance, it took 18sec to process a CSS file with 663 instances of 'url()'.
> It might help, if we add option to specify 'exclusions' with certain CSS resources.
> PR: https://github.com/apache/wicket/pull/147
