This depends on your scripts, it’s up to you to decide whatever their  
results are cacheable or not.

I need some help on “FASTCGI(PHP) CACHE PURGE”.

I successfully configured my nginx to support purge fastcgi cache with  
Ctrl+F5,while I found that I can not purge the cache by request a uri  
like below:

[http://myserver.com/purge/test.php](http://myserver.com/purge/test.php)  
OR  
[http://myserver.com/purge/myserver.com/test.php](http://myserver.com/purge/myserver.com/test.php)

It always returns a 404 error ☹

HOW CAN I DO IT? Please help me~

Here is the key part of my nginx.conf:

* * *

http {  
include mime.types;  
default\_type application/octet-stream;

…

fastcgi\_cache\_path /tmp/fastcgi\_cache levels=1:2 keys\_zone=TEST:10m

```
 ...

```

server {  
listen 80;

index index.html index.htm index.php;

```
if ($request_method = 'PURGE') {
  rewrite ^(.*)$ /purge$1 last;
}

if ($http_cache_control ~ "no-cache") {
  set $http_cache_control 'max-age=604800';
  rewrite ^(.*)$ /purge$1 last;
}

location ~ /purge(/.*) {
  #allow 127.0.0.1;
  #deny all;
                fastcgi_cache_purge TEST $host$1$is_args$args;
}

location ~ .*\.(php|php5)?$ {
  fastcgi_pass unix:/tmp/php-cgi.sock;
  fastcgi_index index.php;
  fastcgi_split_path_info ^(.+\.php)(.*)$;
  include fcgi.conf;
}

                            ...

log_format access '$remote_addr - $remote_user [$time_local]

```

Hi,  
assuming that you didn’t change order of locations during copy & paste  
(which _is_ important) then accessing  
“[http://myserver.com/purge/test.php](http://myserver.com/purge/test.php)”  
should purge content which is normally available under  
“[http://myserver.com/test.php](http://myserver.com/test.php)”.

If that’s not the case, then please try debugging it  
([A debugging log](http://nginx.org/en/docs/debugging_log.html)) with ngx\_cache\_purge-1.4  
(just  
released) and look for cache-related entries.

Best regards,

This is an interesting feature, would be awsome if this got included in  
the  
core. Can it be made to work based of DELETE (method) requests I wonder?
