This is not correct. In the second case there was indeed a view, but it
was loaded from the local cache on the visitor's machine. What happens
(with some simplification) is that the browser sends a query to the server
indicating that the file be resent only if has been updated since the last
time it was loaded to the user's machine. If it has not been revised, the
server sends a message indicating no change and your browser pulls the file
out of your local cache. Saves bandwidth, but it really is a true view of
your banner.
There is also a lot more information you can pull out of your access log if
you so configure your system. This can include the type of browser the
visitor is using, which host is being accessed, and the web page the person
was on when they linked to your site -- absolutely critical information to
evaluate the effectiveness of any PR you do.
A typical line from our log looks like:
warp.cc.monash.edu.au - - [13/Aug/1996:02:33:15 -0500] "GET /online-ads/
HTTP/1.0" 200 4576 arganet.tenagra.com
"http://www.peg.apc.org/~man/welcomh.html#intww" "Mozilla/1.2N (Windows;
I;16bit)"
This tells us that it was an access to the home page of this mailing list
on the arganet.tenagra.com host (there are about 25 virtual hosts on this
particular server), the visitor was using Netscape 1.2N for Windows, and
they linked from the Maryborough Internet Directory in Australia to find
the list.
