Hello,
I have been watching my logs pretty good here lately and I was wondering if anyone could explain this phenomenon. Usually when a user dials his ISP (in this case AOL) he is assigned a single IP address. It appears that this user is being assigned a different IP for every request that the client makes. I think the log generator uses $ENV{'REMOTE_HOST'}, but it appears to be using $ENV{'REMOTE_ADDR'}. I have several domains with this hosting company. Some of the logs give the host name, some give the IP.
The reason I am asking this is because it is a common practice for me to use $ENV{'REMOTE_ADDR'} as a session tracker. I am now wondering if this is going to work. Thanks for any input.
Here is a segment from my logs...
