[Seaside] OT - books on modern web application development

[Wwas]

Hi,

This is slightly OT, but I'm looking for recommendations on texts that 
cover modern web application development. 

I have a techicnal background and have just started studying Sqeak/ST
programming. The ideal book would cover web application architecture
concepts that are applicable to/supported by the Squeak/Seaside
programming environment. 

Thanks,
