Welcome to WebmasterWorld Guest from 18.104.22.168
Often there will appear two log entries for the same GET, within one second of each other. This does not happen consistently. Sometimes there are no duplicate records, very infrequently three records. I've verified that these are for the exactly identical values of $_SERVER['HTTP_REFERER'], and that these calls appear only once in the source code flow of logic.
What might be the cause?
within one second of each other.
The second is just a "suspicion" of mine. I'm on satellite, and satellite is inherently a proxy server. My requests are sent to the proxy and routed through. Sometimes I suspect something gets hosed up in the routing and the proxy doesn't "know" if a request got through so it sends it again. I have no facts to verify this, but over the course of time I've experienced some oddities on some resources - for example, quite often on this site I get a double post and am not sure if this is an issue with the server here or my connection.
My web site is on a GoDaddy (just did a search to verify that it's OK to mention them) shared server. Could this set-up relate to your second scenario?
In any case, thanks.
