exclude some urls containing function codes like ? =, might help...
well i think it depends on what type of cms u r using...
and go through ur webpages to find out the depth level like
bbs.anztrip.com/xxx/xxx/xxx.html this is a fourth level link, the deepest level for my website, then set it 4 in my case...
as for max_execution _time, it does not need to be changed at all, cuz the generator will overite the php.ini file's setting?
the only thing needs to be changed is memeroy limit..make it bigger to start with and reduce it later on once u figure out the best size?
i am also a newbie from Australia...hope any pros can help as well.
