I'd like to write an ACL that compares the integer value of a cookie
with a constant. (My goal is to be able to block percentiles of our
users if we have more traffic than we can handle, so I want to block a
request if the cookie's value is, say, less then 25.)
I understand that I can do something like
hdr_sub(cookie) -i <regular expression>
but that doesn't let me treat the value as an integer and compare it.
I also know about
hdr_val(<header>)
but that gives me the entire value of the cookie header, not just the
value of a particular cookie.
Is there any way that I can do this?
