First, add a / in front of the uri according to Davids suggestion, then add the extra \r\n according to crodriguez:
Result:
GET /Default.aspx HTTP/1.1\r\nHost: sharepointsites.abc.com\r\n\r\n
I don't think it matters, but you might also want to add a user-agent if you want to make the request more "real":
GET /Default.aspx HTTP/1.1\r\nHost: sharepointsites.abc.com\r\nUser-agent: Mozilla/5.0 (LB;Windows NT 6.1;)\r\n\r\n
Then, you can troubleshoot by going to the pool, clicking on a member, then clicking on the monitor and then enable "Monitor Logging".
Check the logs in
/var/log/monitors/
and you should have more to go on.
I would also check the IIS logs to see if the request has been accepted by filtering for the load balancers self IP on the c-ip column.
Another thing you can do is to run a tcpdump and check the results in Wireshark:
tcpdump -vvv -s0 -nni any host and host and port -w /var/tmp/sharepoint.pcap
Wait a few seconds to get a few packets (you can see the counter in the shell prompt) and then download and open the file in wireshark.
Good luck!
