I don't know. Probably not, but it's sometimes convenient to do so. Well, I've did so when I had to debug some redirect caching problem with "walled garden" setup. This could also be done with a more specialized software, though, I just happened to use telnet as it was readily available. I also sometimes check server's availability (and overall response correctnes) by telnetting to it. Although, I was just too lazy to set up a tunnel to the LAN they're residing at.
