cache miss

This is my basic modifications for woocomerce:
#### woocomerce cookie
# Unset Cookies except for WordPress admin and WooCommerce pages
if (!(req.url ~ “(wp-login|wp-admin|cart|my-account/*|wc-api*|checkout|addons|logout|lost-password|product/*|courses/*)”)) {
# set req.http.X-VC-Cacheable = “NO:dynamic logged in cookie”;
unset req.http.cookie;
}
# don’t cache these special pages. Not needed, left here as example
if (req.url ~ “courses/*|cart|my-account|checkout|addons|nocache|wp-admin|wp-(comments-post|login|activate|mail)\.php|bb-admin|server-status|control\.php|bb-login\.php|bb-reset-password\.php|register\.php”) {
set req.http.X-VC-Cacheable = “NO:Special page: ” + req.url;
return(pass);
}

### another skip pages
if ( req.url ~ “\?add-to-cart=” ) {
set req.http.X-VC-Cacheable = “NO:Special page: ” + req.url;
return (pass);
}
