URLs aren’t files. All the kernel knows about a network connection is the IP
address and TCP port number it’s connected to. It has no idea what protocol
it’s using (HTTP, FTP, IMAP, whatever) or any protocol-specific details like
the HTTP path. So no, you can’t derive a URL from the list of open sockets. All
you can get is
???://name.of.host:port/????
If you want to sniff all HTTP traffic, which will let you see the paths in the
request lines, you can use something like tcpdump. (But it would probably be
hard to identify only the HTTP traffic, unless you limit yourself to port 80.)
