[Seaside] handleRequest: and Seaside 3

[Martin Polák]

Hi there,
	In my Seaside 2.8 application I have overriden #handleRequest: method  
of WAApplication to return WAResponse for some particular URL. For  
example for http://localhost:8080/app/items.xml it returned XML with  
all items. Now in Seaside 3, there is no #handleRequest: in  
WAApplication and I'm not sure, how to achieve the same functionality.  
Any suggestions, please?

Thanks,
Martin
