If anyone is on an Apache list that this seems appropriate to please forward it there or reply to me with the list name, I do not know of one.
In my Apache log files with Referrer and User-Agent turned on a significant proportion (around 25%) of the referer logs appear as "-". Can anyone tell me what causes this? I need to know whether these are likely to follow the same pattern as completed references or if there is a particular reason that skews the data. They are easily the largest group of referers and misinterpreting them could cause us to make some very serious errors. Jeff Green
