I've had more than one person come to me and ask something down the lines of "I'm drawing a blank. Can you think of a good tutorial I could write?" Since I'm almost always in the middle of trying to figure something out, I can usually come up with at least one or two. I'm sure there's plenty others like me who have stuff they'd like to learn but have yet to see a tut on it.

So, I'm starting this thread in GCC in hopes that it will provide a medium to a) help less knowledgable members request information and b) give a pool for people looking to write tutorials to choose from.

So that said, there are two topics I'd like to see tutorials on. I don't know much about either of these myself:

1) HTTP Tunneling.
2) Methods of web security (example: HTTPS).

So if you're looking to write a tut but can't think of anything, I'd suggest one of those two.
