Hi there,
since Monday, many of my tiny monitoring checks (analyse web pages for
changes or specific content) where I used curl just fine over _years_
suddenly fail with HTTP 403 access denied. While investigating, I found
out that these pages are all "protected" by Cloudfare. If I use a
browser (Firefox) go to one of these webpages I see the message as in
the image attached.
It basically says:
"[Homepage name] must check the security of your connection"
And then, at the bottom a Cloudfare reference "Ray ID" is shown as well
as a Cloudfare slogan.
As an example to reproduce: You can use any project page on sourceforge.net
To rant a little: I don't now whats wrong with the internet these days
and why such checks are required at all. I am sure they break a lot of
applications like mine! (Rant off.)
Now, I found many reports and "solutions" that are related to that issue
(like manipulating the header sent, setting cookies etc.) but they are
_all_ not working in these cases.
I am sure I am not the only one and now I am searching here for answers
because I believe many curl users are affected, too. Please help me! :-)
Best regards,
Morten.
