Par d\u00e9faut, si vous utilisez la configuration en malloc sans option, varnish cr\u00e9e un espace de stockage nomm\u00e9 s0 en ram.
\nMais vous pouvez utiliser plusieurs stockages en ram ou sur disque pour garantir des performances en fonction de votre besoin.
\nPar exemple, pour qu’un site ne remplisse par le cache et impacte sur un autre :
\n– Dans le fichier \/etc\/default\/varnish<\/p>\n

DAEMON_OPTS=\"\r\n...\r\n-s default=malloc,64m \\\r\n-s foo=malloc,128M \\\r\n-s bar=malloc,128M \\\r\n...\"<\/pre>\n
– Dans vcl_backend_response (4.0) :<\/p>\n
if (bereq.http.host ~ \"foo\") {\r\n       set beresp.storage_hint = \"foo\";\r\n} else if (bereq.http.host ~ \"bar\") {\r\n       set beresp.storage_hint = \"bar\";\r\n} else {\r\n       set beresp.storage_hint = \"default\";\r\n}\r\n<\/pre>\n
ou vcl_fetch (3.0) :<\/p>\n
if (req.http.host ~ \"foo\") {\r\n       set beresp.storage = \"foo\";\r\n} else if (req.http.host ~ \"bar\") {\r\n       set beresp.storage = \"bar\";\r\n} else {\r\n       set beresp.storage = \"default\";\r\n}\r\n<\/pre>\n
Par exemple, en fonction du TTL :
\n– Dans le fichier \/etc\/default\/varnish<\/p>\n
DAEMON_OPTS=\"\r\n...\r\n-s ram=malloc,1G \\\r\n-s disk=file,\/space\/varnish\/storage,10G \\\r\n...\"<\/pre>\n
– Dans vcl_backend_response (4.0) ou vcl_fetch (3.0)  :<\/p>\n
sub vcl_backend_response {\r\n       # default storage\r\n       set beresp.storage = \"ram\";\r\n...\r\n       if (beresp.ttl > 86400s) {\r\n              set beresp.storage = \"disk\";\r\n       }\r\n}                                                                                                                                                                                                   <\/pre>\n","protected":false},"excerpt":{"rendered":"
