    W3 Total Cache keeps adding this to my header:
    Set-Cookie: w3tc_referrer=

    How do I stop that????? I have everything disabled except browser cache and CDN and it add this cookie to our site.

    What is that? How do you disable that???

    Example:
    HTTP/1.1 200 OK
    Content-Type: text/html; charset=UTF-8
    Content-Encoding: gzip
    Vary: Accept-Encoding
    Set-Cookie: w3tc_referrer=http%3A%2F%2Fwww.google.fr%2Furl%3Fsa%3Dt%26source path=/

    In the case where referrer isn't set. W3TC sets a cookie so it can ensure the correct user experience.

    The strange thing with this cookie is that it load twice the page request slowing down the load.

    How to prevent this ?

    I have the same question, how can I remove this cookie? Additionaly the cookie exposes the full local pathname where wordpress is located.

    Set-Cookie: w3tc_referrer=http://domain.tld/referrer; path=/var/www/path/to/wordpress

    I guess this has possible security implications.

    Frederick, what do you mean by:

    In the case where referrer isn't set. W3TC sets a cookie so it can ensure the correct user experience.

    How will users experience referrer set vs. referrer not set?

    Hi all,

    I am also trying to find out how to remove this cookie or where it is set to control when it gets set.

    The new EU cookie laws make it a requirement to ask people permission to set certain cookies. Has anyone made any progress finding out where total cache does this?

    I have tried setting up referrer groups and leaving them empty, but the cookie is set regardless.

    Has anyone located it?

    Thanks in advance!
