It's the first time ever that I have seen this cloudflare thing
and had to declare I wasn't a robot!!!!

Lucky you, I have been getting that from them for over a year.
Sometimes I am graced with a captha.

How prevalent is it? I've tried deleting cookies etc and NOT managed
to get it to ask again. Anyone explain?

I do not know how cloudflare works, but if I get it I just
bail, thinking going to that WEB Site is not worth my time.

Now the interesting thing, I never get Cloudflare when I log
into my Bank's site. That alone tells be Cloudflare is
doing something I believe is something you would not want
them to do. I almost suspect Cloudflare is examining your
browser cache and maybe cookies. Yes I put my tinfoil hat
on when Cloudflare prompts me :)

cloudflare actually run some DNS as well, on 1.1.1.1 and 1.0.0.1 and
provide websites with defences against DDoS attacks.

Does your bank use Cloudflare for caching at all? If they don't use it,
you won't have any issues with it.

I do not do any real on-line banking, I only login once per
month to get the statement.

That's nice but irrelvant. Do they cache with cloudflare?

Cloudflare is likely setting cookies in your browser in order to keep track >> of connections, since you might have nultiple cloudflare-cached websites
open at the same time.

Cloudflare is not examining your browser cache, it is in part replacing it.

You are probably correct, but the real question is "How can
we prove it ?". Luckily OpenBSD has pledge(2) and unveil(2),
so what ever Cloudflare examine is very limited :)

You can read Cloudflare's documentation for their customers which explains
how their caching system works and why web providers would want to employ
it. It's all very well-documented. I have not read their stuff about
cookie management since I have mostly been interested in how they determine which site you are trying to access through their system and how they make
sure they send you the right website.

I have no idea, I do not get Cloudflare capthas from cloudflare
when I go to the site. That is a big plus for me.
