Skipping the proxy cache based on a cookie?

[Dayo]

Hi all

I doesn't seem that "if ($cookie_COOKIE = "") {" is a valid test for the
presence of a cookie as the code in the if statement does not seem to be
run.

I am using ...

[code]
if ($cookie_COOKIE = "") {
add_header Set-Cookie: "hits = 1";
}
[/code]

... but no joy. (I tried the original suggestion first)

Open to further suggestions

Thanks
