Not really - you will always have to check remotely 
ALL files to see if some of them have been updated if 
you select the 'Update' function. You can not update 
only index.html file and ask the engine NOT to check 
other files. Update requests are faster and takes few 
bandwidth, but it can still overload a bit a server..
