Yes. But it depends upon the kind of data served. The header size is quite fixed, but the payload size may vary. A site with loits of small replys will have a percentage more like 60%. Furthermore, apache doesn't take into account *incoming* traffic, whereas your hosting provider probably does (ie counts in both directions). There can be great differences here if you do a lot of "posting" (like posting big files, for instance). > > PS: we pay for the traffic "on the cable" and webalizer only gets the > "pay-load" from http. > Then use net-acct to get the real values. Unfortunatly, there's no way to figure out the data for various virtual servers which share the same IP. -- Nicolas BOUGUES Axialys Interactive
