Memcached problems

Hallo folks again,

i try to configure nginx to deliver swf files etc, and wanted to cache
them within memcached. but until now i didnt have much success with
that.
what i already did:

include/excluded parts of the config (flv part, swf part & php part) and
tested them one by one. no change… but if i try to open a sfv file via
browser i see that nginx communicates with memcached and this error
messages appears in the nginx error log (without the memcached part in
the config i get the file as download, like expected)

2009/08/31 18:34:40 [info] 23808#0: *1 key:
“/files/_somewhere/xxx/xxxx.flv” was not found by memcached while
reading response header from upstream, client: 62.
116.129.3, server: media, request: “GET /files/_somewhere/xxx/xxxx.flv
HTTP/1.1”, upstream: “memcached://127.0.0.1:11211”, host: “ftp.xxx.org:8
1”

it seems that nginx looks in memcached for the file, but it has not yet
read from the disk so nginx cant find it inside memcached and throws me
a 404

heres my nginx.conf

http {
include /etc/nginx/mime.types;
default_type application/octet-stream;

 log_format  main  '$http_host $remote_addr - $remote_user

[$time_local] $request ’
'"$status" $body_bytes_sent “$http_referer” ’
‘"$http_user_agent" “$http_x_forwarded_for”’;

 access_log  /var/log/nginx/access.log  main;

 sendfile        on;
 tcp_nopush     on;

 #keepalive_timeout  0;
 keepalive_timeout  65;

 #gzip  on;
 server {
     listen       81;
     server_name  media;

     #charset koi8-r;

     #access_log  logs/host.access.log  main;


     location / {
         root   /home/www/htdocs;
         index  index.html index.htm;


     error_page  404     http://failover.somewhere.de/404.html;

     location ~ \.flv$ {
         memcached_pass 127.0.0.1:11211;
         set $memcached_key $uri;
         root           /home/www/htdocs;
     }

     location ~ \.swf$ {
         set $memcached_key $uri;
         memcached_pass     127.0.0.1:11211;
         root           /home/www/htdocs;
     }

  location ~ /\.ht* {
         deny  all;
     }
  }

}

How big are your swfs? I believe that memcached by default can only
store a
value up to 1MB. Also, I’m not positive what benefit you would receive
by
caching the file in memcached because I believe the file would already
be
cached by the filesystem.
