I've noticed 404's in my logs of people trying to get to /null on my site. I've always assumed that was hackers/probes and I just ignored it. But today I happened to pull up my site in Netscape 4.78 and noticed that about half the time it loads my page, then immediately tries to redirect to /null. My real page loads completely, then the /null thing happens.
I have google ads running, is it an IFRAME thing?
Thanks for any insights!
