right looks extracting data httpdstatistics htmlgenerator object, using build reply. want make httpdstatistics object accessible outside class, right?

i don't know happens inside getserver().getstatistics(), add "getter" method return that? use getter internally in get(), avoid code duplication. like:

public httpdstatistics getstats() { return ((httpd)getserver()).getstatistics(); } 

and in get():

httpdstatistics stats = getstats();
