Hi, i have a question about limit/offset.  i read something that says if you're doing something like pages of results with next/previous buttons, you should do the query once and then cache the results for a certain period of time, but then my friend says you can do limit(x,y) where, i guess, one variable is the starting point and the other is the number of records.  then i found out about the "offset" keyword on the web, so i guess the proper way is to use limit and offset.  either way, this seems more efficient than caching the whole query--is it?  and how do i do this in sqlobject?  or should i just store a query and use slicing on it?  or just do the same query each time and use slicing on it since sqlobject caches certain things anyway?  thanks.
