For anyone who can't get the fastcgi cache to work...

I noticed in my website that when cart is empty , the headers don't have a set cookie for woocommerce_items_in_cart.
It is not woocommerce_items_in_cart = 0 , it just doesn't exist.
If this is the case for you , change the code :

if ( $cookie_woocommerce_items_in_cart != "0" ) {
set $skip_cache 1;
}

to:

#true only when the cookie exists
if ( $cookie_woocommerce_items_in_cart ) {
set $skip_cache 1;
}

For me when I add to cart and then make cart empty again , the cookie just disappears, so you can just go ahead and only check for it if it exists.

Some lines of code are missing that causing an error, here is what I found:

• On the line 20:

if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_n$

should be:

if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {

• The line 45:

try_files $uri /wp-content/plugins/w3-total-cache/pub/minify.php?file=$$

should be:

try_files $uri /wp-content/plugins/w3-total-cache/pub/minify.php?file=$1 /index.php;

You forgot one...

  • On line 15

if ($request_uri ~* "(/wp-admin/|/xmlrpc.php|wp-.*.php|index.php|/feed/|sitemap$

should be:

if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml") {
