I saw several entries like the below in my access log.

I'm baffled by these. They show websites that my wife was visiting
from our machine. 127.0.0.1 is localhost, and it shows "GET
/collect.jsp" followed by the URL she was visiting and also what I
presume is the referrer URL. (She clicked a link on hitched.co.uk
which took her to isabellaoliver.com - she's due in August )

What I can't fathom is why her browsing history is ending up in
my apache2 access.log?

(Apologies for wrap).
