Jim, thanks for your answers!
Answer 1 is right what I thought it would be. That's ok.
The on-server logfile analyzer you recommend for my second question is what I come to from my control panel as well, I think. It's indeed very good. I had never seen it before and i love it. But I did ask that question about converting IPs in my raw log files to meaningful host names, because this on-server AWstats does NOT give us hostnames, just IPs. AWstats is wonderful, but its reports could be much more meaningful with hostnames instead of IP numbers.
To my third question, which is not about whatever downloaded file in my subdomain, but e.g. about the subdomains index.htm file (I expressed myself unclear the first time).
Reading both the online AWstats reports and the raw log file shows, that nothing, even not the index.htm file of the subdomain is tracked when accessing it via subdomain.rahn.net/index.htm. But if I access it via
www.rahn.net/subdomain/index.htm, then it's indeed tracked in the log file and also shows up in the online statistics package.
It's this discepancy that I think is a bug, not some obscure download that's left untracked.
Subdomains are meant to be used opf course, so basically all of
my visitors come using the subdomain URL, and none of them shows up in my stats.
This last point is the most important for me. Now that I stated it more clearly, could you please check again if this behaviour is normal or not?
Many thanks for your replies !
