[ybrant apache]

Hi All,
I need Apache C API documentation or tutorials for Apache 2.0. Please let me know if any body knows good links to them or books.

I have book "Writing Apache modules with perl and C". but for Apache 1.3.

I hope there were lot of changes with 1.3 and 2.0
So if any body knows the details, please provide as it is very urgent.

Thanks in Advance.

Thanks & Regards,
YbrAdd.
