Nick Belaevski commented on RF-3273:
------------------------------------

That won't work right for all possible cases, because component subtree that is being replaced on the client can be modified during AJAX request so that it contains components that weren't there previously. E.g. components added programmtically, usage of c:if tags or page included using a4j:include.

> There is an expectation that Ajax responses are reasonably small. However, RichFaces Ajax responses are unreasonably large because the BaseXMLFilter is mistakingly sending the entire <head> tag regardless of whether the response type is Ajax or not. The <head> tag contains many <script> and <link> tags that bloat the response. The BaseXMLFilter should only be sending the <head> tag on a normal response.
> Now you might think, "What if the region to be rendered has new components (that were not previously rendered) for which styles and scripts are necessary for proper behavior?" Well, RichFaces is already smart and incorporates these styles and scripts into the initial response even if the associated components are not rendered. So there is absolutely *no* reason to have them sent in the Ajax response.
