워드프레스 Varnish 4.0 default.vcl

워드프레스 Varnish 4.0 default.vcl

구글링을 해보면 워드프레스 최적화를 위한 varnish 세팅이 많이 있는데 대부분 3.0버전 대의 vcl이라서 varnish 4.0 버전에서는 에러가 난다. 최근에 찾은 varnish 4.0용 가장 핫한 default.vcl 세팅이다.

 


 

 

# This is my VCL file for Varnish 4.0.2 & WordPress 4.0
#
# ASSUME The builtin VCL is called afterwards.
#

# Specify VCL new 4.0 format.
vcl 4.0;

# Imports
import std;

# Default backend definition. Set this to point to your content server.
backend default {
.host = “127.0.0.1”;
##.port = “8080”;
.port = “8888”;
}
acl aclPurge {
# For now, I’ll only allow purges coming from localhost
“127.0.0.1”;
“localhost”;
}
acl aclBanned {
# Private Networks 192.168.*.* [subnet mask /16 = netmask 255.255.0.0 = 16 meaningful bits left to right]
“192.168.0.0”/16;
# some specific malicious ip addresses
“81.82.83.84”;
“31.5.89.4”;
}

sub vcl_recv {
### DOC
# https://www.varnish-cache.org/docs/4.0/users-guide/vcl-built-in-subs.html#vcl-recv
# http://www.mediawiki.org/wiki/Manual:Varnish_caching#Configuring_Varnish_4.x
# – The builtin VCL is always called afterwards.
# – Happens before we check if we have this in cache already.
# – Typically you clean up the request here, adjusting headers, managing cookies, rewriting the request, etc.

### vmod std:
# – std.log(str): Logs a string to the shared memory log, using VSL tag VCL_Log
# – varnishlog -i VCL_Log

###
### Allow purging
###
# Tip: it only purges the current cache entry (to purge the whole cache: do service restart instead)
if (req.method == “PURGE”) {
if (!client.ip ~ aclPurge) {
return (synth(405, “This IP is not allowed to send PURGE requests.”));
}
return (purge);
}

###
### Banning Logic (replacing the WordPress Plugin WP-Ban)
###

# IP Addresses 192.168.*.
if (client.ip ~ aclBanned) {
return (synth(403, “Forbidden”));
}

###
### Do not Cache: special cases
###

### Do not Authorized requests.
if (req.http.Authorization) {
return(pass); // DO NOT CACHE
}

### Pass any requests with the “If-None-Match” header directly.
if (req.http.If-None-Match) {
return(pass); // DO NOT CACHE
}

### Do not cache AJAX requests.
if (req.http.X-Requested-With == “XMLHttpRequest”) {
return(pass); // DO NOT CACHE
}

### Only cache GET or HEAD requests. This makes sure the POST (and OPTIONS) requests are always passed.
if (req.method != “GET” && req.method != “HEAD”) {
return (pass); // DO NOT CACHE
}
###
### Request URL
###

# Apache: disable caching for the Apache2 server status page
if (req.url ~ “^/server-status”) {
# do not use the cache
return(pass); // DO NOT CACHE
}

### Static files: Do not cache PDF, XML, … files (=static & huge and no use caching them – in all Vary: variations!)
if (req.url ~ “\.(doc|mp3|pdf|tif|tiff|xml)(\?.*|)$”) {
return(pass); // DO NOT CACHE
}

# WordPress: disable caching for some parts of the backend (mostly admin stuff)
# and WP search results.
if (
req.url ~ “^/wp-(login|admin)” || req.url ~ “/wp-cron.php” || req.url ~ “/wp-content/uploads/”
|| req.url ~ “preview=true” || req.url ~ “xmlrpc.php” || req.url ~ “\?s=”
) {
# do not use the cache
return(pass); // DO NOT CACHE
}

# Development: my /tryme/ folder with test scripts
if (req.url ~ “^/tryme/”) {
# do not use the cache
return(pass); // DO NOT CACHE
}

# WooCommerce
if (req.url ~ “\?add-to-cart=”) {
# do not use the cache
return(pass); // DO NOT CACHE
}

# Kick DFind requests
if (req.url ~ “^/w00tw00t”) {
return (synth(404, “Not Found”));
}
###
### http header Cookie
### Remove some cookies (if found).
###
# https://www.varnish-cache.org/docs/4.0/users-guide/increasing-your-hitrate.html#cookies

# Unset the header for static files
if (req.url ~ “\.(css|flv|gif|htm|html|ico|jpeg|jpg|js|mp3|mp4|pdf|png|swf|tif|tiff|xml)(\?.*|)$”) {
unset req.http.Cookie;
}

if (req.http.cookie) {
# Google Analytics
set req.http.Cookie = regsuball( req.http.Cookie, “(^|;\s*)(__utm[a-z]+)=([^;]*)”, “”);
set req.http.Cookie = regsuball( req.http.Cookie, “(^|;\s*)(_ga)=([^;]*)”, “”);

# Quant Capital
set req.http.Cookie = regsuball( req.http.Cookie, “(^|;\s*)(__qc[a-z]+)=([^;]*)”, “”);

# __gad __gads
set req.http.Cookie = regsuball( req.http.Cookie, “(^|;\s*)(__gad[a-z]+)=([^;]*)”, “”);

# Google Cookie consent (client javascript cookie)
set req.http.Cookie = regsuball( req.http.Cookie, “(^|;\s*)(displayCookieConsent)=([^;]*)”, “”);

# Other known Cookies: remove them (if found).
set req.http.Cookie = regsuball( req.http.Cookie, “(^|;\s*)(__CT_Data)=([^;]*)”, “”);
set req.http.Cookie = regsuball( req.http.Cookie, “(^|;\s*)(WRIgnore|WRUID)=([^;]*)”, “”);
# PostAction: Remove (once and if found) a “;” prefix followed by 0..n whitespaces.
# INFO \s* = 0..n whitespace characters
set req.http.Cookie = regsub( req.http.Cookie, “^;\s*”, “” );

# PostAction: Unset the header if it is empty or 0..n whitespaces.
if ( req.http.cookie ~ “^\s*$” ) {
unset req.http.Cookie;
}
}
###
### Normalize the Accept-Language header
### We do not need a cache for each language-country combination! Just keep en-* and nl-* for future use.
### https://www.varnish-cache.org/docs/4.0/users-guide/increasing-your-hitrate.html#http-vary
if (req.http.Accept-Language) {
if (req.http.Accept-Language ~ “^en”) {
set req.http.Accept-Language = “en”;
} elsif (req.http.Accept-Language ~ “^nl”) {
set req.http.Accept-Language = “nl”;
} else {
# Unknown language. Set it to English.
set req.http.Accept-Language = “en”;
}
}
###
### Varnish v4: vcl_recv must now return hash instead of lookup
return(hash);
}

sub vcl_backend_response {
# Happens after we have read the response headers from the backend.
# Here you clean the response headers, removing silly Set-Cookie headers
# and other mistakes your backend does.

# main variable = beresp.
}

sub vcl_deliver {
# Happens when we have all the pieces we need, and are about to send the
# response to the client. You can do accounting or modifying the final object here.

# main variable = resp.

set resp.http.Server = “mine”;
set resp.http.X-Powered-By = “electricity”;
}

sub vcl_pipe {
# https://www.varnish-software.com/blog/using-pipe-varnish
# Note that only the first request to the backend will have X-Forwarded-For set.
# If you use X-Forwarded-For and want to have it set for all requests,
# then make sure to use this: set req.http.connection = “close”;
# (This code is not necessary if you do not do any request rewriting.)

set req.http.connection = “close”;
}
