I was mostly just wondering about differences between using things like `capture request header`/`http-request capture` and `http-request set-var`.
set-var seems to have all the capabilities of captures, and are much easier to work with. You don't have to pre-declare them, you don't have to set their size, you don't have to remember the order in which you declared them and reference them by an index. So what's the benefit of captures? Are they more performant or something? -Patrick
