Squid configuration directive negative_ttl

This directive is not available in the v8 version of Squid.

For older versions than v5 see the linked pages above


Option Name:	negative_ttl
Replaces:
Requires:	--enable-http-violations
Default Value:	negative_ttl 0 seconds
Suggested Config:
Set the Default Time-to-Live (TTL) for failed requests. Certain types of failures (such as “connection refused” and “404 Not Found”) are able to be negatively-cached for a short time. Modern web servers should provide Expires: header, however if they do not this can provide a minimum TTL. The default is not to cache errors with unknown expiry details. Note that this is different from negative caching of DNS lookups. WARNING: Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes.
