Dear integrators,

Hope you enjoyed your holidays. I have been trapped in Estonia due to a blizzard, and had no choice but to stay with my friend Tommy.

Tommy and I sat in front of the fireplace to keep warm after dinner.

"It's really cold, isn't it?" I said.

"Doc, I have to apologize to you. You came here to bring me a new camera and now you're stranded."

"Never mind that, Tommy. You can't control the weather, and I'm getting a free room, great food and all the beer I can drink here. You've really made me feel at home. No apologies needed!" I answered him, smiling.

"Thanks, Doc. If you'll excuse me, I need to check how much snow has piled up outside," said Tommy.

"You're going outside? It's freezing out there!" I exclaimed in disbelief.

"Did you forget, Doc? I've got network cameras I can use to check," Tommy reminded me.

"Oh, that's right," I said. I was all for checking how much snow there was ... as long as nobody had to go outside and freeze to do it.

Tommy and I went to the control room and looked at the view on the monitor.

I spotted something moving, and-excitable guy that I am-yelled to Tommy, "Move the camera left! I think it's a squirrel!"

"Stop," I said. "Stop... stop... stop! You overshot it!" By the time he moved the camera back, my little snow-loving friend was nowhere in sight.

"Well, I think we have a latency problem here," Tommy said, trying to explain how he missed the area he was trying to focus on.

"Tommy, don't you use a tunnel connection to the camera?" I asked.

"Tunnel connection? What is that?" Tommy asked.

"It's a type of live connection. By sending commands through the tunnel, there's no need to create a new connection for each command. That way, you get a more real-time response," I answered.

"Sounds great, Doc. You'll have to show me how to set one up," Tommy said.

"Sure" I said.

If you're interested in learning more about tunnel connections, like Tommy was, you can download the application note about HTTP tunnels. Hope this helps.
