odd little things

I just noticed that whenever I load up my friends page LJ redirects me through this:

http://zwol.livejournal.com/__setdomsess?dest=http://zwol.livejournal.com/friends/&k=ljdomsess.zwol&v=(elided)//Thanks+for+signing+in+/+LiveJournal+loves+you+a+lot+/+Here+have+a+cookie

I wonder how long that's been there...
