Consider that we publish probably around 50-60 posts each day…does the cache get completely emptied each time?

Dear Matt,

our include is at the end of the nginx.conf file in the http block

include /etc/nginx/conf.d/*.conf;

Here is our updated version of the wf.conf file:

server {
# WORDFENCE FALCON ENGINE CODE
#Match on gzip first because ordering matters.
location ~ "/usr/share/nginx/www/wp-content/wfcache/.*gzip$" {
gzip off;
types {}
default_type text/html;
add_header Vary "Accept-Encoding, Cookie";
add_header Content-Encoding gzip;
}
#If the previous matched, the following location won't be executed.
location ~ /usr/share/nginx/www/wp-content/wfcache/.* {
add_header Vary "Accept-Encoding, Cookie";
}
set $wordfenceCacheOn 1;

#Don't cache form submissions.
if ($request_method = POST) {
set $wordfenceCacheOn 0;
}

#Allow caching of /?123=123 because this is a common DDoS to override caches.
if ($query_string !~ "^(?:d+=d+)?$") {
set $wordfenceCacheOn 0;
}

#Only cache URL's ending in /
if ($request_uri !~ /$) {
set $wordfenceCacheOn 0;
}
#Don't cache any cookies with this in their names e.g. users who are logged in.
if ($http_cookie ~* "(comment_author|wp-postpass|wf_logout|wordpress_logged_in|wptouch_switch_toggle|wpmp_switcher)") {
set $wordfenceCacheOn 0;
}
set $wordfenceEncoding "";
#Oh, you want gzipped content?
if ($http_accept_encoding ~ gzip) {
set $wordfenceEncoding _gzip;
}
set $wordfenceHTTPS "";
if ($scheme = 'https'){
#If you want to ENABLE HTTPS caching, comment out the next line.
set $wordfenceCacheOn 0; #Comment this line out to enable HTTPS caching.

set $wordfenceHTTPS '_https'; #Uncomment this line to enable HTTPS caching.
}
#The main purpose of this line is to capture the URL components into variables.
if ($request_uri !~ "^/*(?<wfone>[^/]*)/*(?<wftwo>[^/]*)/*(?<wfthree>[^/]*)/*(?<wffour>[^/]*)/*(?<wffive>[^/]*)(?<wfsix>.*)$"){
set $wordfenceCacheOn 0;
}
#If the file doesn't exist then don't serve from cache.
if (!-f "$document_root/wp-content/wfcache/${http_host}_${wfone}/${wftwo}~${wfthree}~${wffour}~${wffive}~${wfsix}_wfcache${wordfenceHTTPS}.html${wordfenceEncoding}") {
set $wordfenceCacheOn 0;
}

if ($wordfenceCacheOn = 1) {
rewrite .* "/wp-content/wfcache/${http_host}_${wfone}/${wftwo}~${wfthree}~${wffour}~${wffive}~${wfsix}_wfcache${wordfenceHTTPS}.html${wordfenceEncoding}" last;
}
# END Wordfence Rules
}

Could it be that the problems is that we continually create posts and update them so the cache get purged too often? Because we still don’t see any improvement…
