<sesskey> is the Session ID that you got from N-server 242 while logging in (LOGIN)
<profileid> is your profile ID (not the same as the user ID). You've also got this while logging in.
<friends count> is the number of friends in your friends list

After "opids" there are the user IDs of your friends, seperated by an "|".
