Hi!
This is the first time I am doing rewrites with a fastcgi backend
(php-fpm).
This is my fpm location which is working fine on a ubuntu 18.04 VM:
# fpm-config
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php-fpm-typo3.sock;
fastcgi_param HTTPS 'on';
fastcgi_read_timeout 240;
# cache settings
fastcgi_cache html_cache;
fastcgi_cache_valid 200 404 60m;
fastcgi_cache_bypass $no_cache_allowed;
fastcgi_cache_bypass $cookie_be_typo_user;
fastcgi_cache_bypass $eID_search_no_cache;
}
in the http section:
http {
...
...
fastcgi_cache_path /var/cache/nginx/proxy_cache levels=1:2
keys_zone=html_cache:10m max_size=5120m inactive=60m use_temp_path=off;
fastcgi_cache_key "$scheme$request_method$host$request_uri";
fastcgi_buffer_size 128k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
...
}
After adding this location in the fpm vhost the caching is not working
as expected and delivers the same page for each request:
location ~ ^/hotel/([0-9]+)/.* {
rewrite ^/hotel/([0-9]+)/.*
/index.php?id=3238&user_kuoniibefe_pi3[iff]=$1 break;
include snippets/fastcgi-php.conf;
fastcgi_param REQUEST_URI
$fastcgi_script_name?$query_string;
fastcgi_pass unix:/run/php/php-fpm-typo3.sock;
fastcgi_param HTTPS 'on';
fastcgi_read_timeout 240;
# cache settings
include /etc/nginx/conf.d/fcgi_cache_settings.inc;
}
The location block is used to rewrite URLs like
/hotel/1234/bla?x=1&...
to
/index.php?h=1234&.....
but in this case the cache key is missing all the query parameters:
2020/10/15 17:27:51 [debug] 825#825: *1 http2 request line: "GET
/hotel/3/bl-zzz-xxxccccresort-spa-antigua/?ddate=2020-11-01&rdate=2021-04-30&adult=2&aid=3&dur=13,15&ibe=package
HTTP/2.0"
2020/10/15 17:27:51 [debug] 825#825: *1 http cache key:
"httpsGETdev1.restplatzboerse.at"
with other URLs the cache key is correct:
2020/10/15 17:27:30 [debug] 32644#32644: *761 http2 request line: "GET
/index.php?id=3238&user_kuoniibefe_pi3[iff]=3&ddate=2020-11-01&rdate=2021-04-30&adult=2&aid=3&dur=13,15&ibe=package
HTTP/2.0"
2020/10/15 17:27:30 [debug] 32644#32644: *761 http cache key:
"httpsGETdev1.restplatzboerse.at/index.php?id=3238&user_kuoniibefe_pi3[iff]=3&ddate=2020-11-01&rdate=2021-04-30&adult=2&aid=3&dur=13,15&ibe=package"
My question is why is the cache key incomplete with request that are
rewritten? How could I get the correct cache key after rewriting the
/hotel/1234/bla request.
The fastcgi_cache_key parameter in the http block is only once allowed,
so I can not use another fastcgi_cache_key parameter in the rewrite
location block.
I found a include file in my vhost that is removing some unwanted query
parameters (to be not part of the cache key). That include was also in
the /hotel rewrite location and removed all query parameters. So I
removed it and the cache key looks now ok.
set $c_uri $args; # e.g. "param1=true¶m4=false"
# get url path into variable for cache_key
set $u_path $request_uri;
if ($request_uri ~ (.*)(\?.*)) {
set $u_path $1;
}
# remove unwanted get params
if ($c_uri ~ (.*)(?:&|^)utm_source=[^&]*(.*)) {
set $c_uri $1$2;
}
if ($c_uri ~ (.*)(?:&|^)utm_term=[^&]*(.*)) {
set $c_uri $1$2;
}
if ($c_uri ~ (.*)(?:&|^)utm_campaign=[^&]*(.*)) {
set $c_uri $1$2;
}
set $c_uri $is_args$c_uri;
if ($c_uri ~ ^\?$) {
set $c_uri "";
}
# finally we have stripped out utms and has nice cache key
set $c_uri $u_path$c_uri;
# DEBUG (disable in prd env)
#add_header X-RURI $request_uri;
#add_header X-CACHE-KEY $c_uri;
#add_header X-U-Path $u_path;
# set cleaned $c_uri as cache_key
fastcgi_cache_key "$scheme$request_method$host$c_uri";
