Do they have something on the outside that makes them not stick to it? Do webs only stick to wing material?

I was lead to believe (although I can't site sources) that only the circular strands have the sticky stuff, the straight strands that all meet at the centre are free of the glue and it comes down to basically the spider knowing where to tread.
