Name

always_direct

Synopsis

The always_direct access rules define a class of requests that must always be forwarded directly to the origin server. For these, Squid doesn’t query or otherwise consider any neighbor caches. See Section 10.4.4.

Syntax

always_direct allow|deny [!]ACLname ...

Default

No default

Example

acl LocalServers dst 172.17.0.0/24
always_direct allow LocalServers
