1.3 Optional Variables Not Necessary For Operation

[SQUID_CONNECT_TIMEOUT]

This option determines how long Squid waits for a full TCP connection to a server. Within this time (default: 120 seconds) the connection to the server must be established.

[SQUID_CACHE_N]

If you want to spread the cache over multiple disks you may activate this here. With this you can specify several additional cache directories. In order to do this the index must be set to the desired number of additional directories.

Now fill the varable [SQUID_CACHE_1_DIR][SQUID_CACHE_1_SIZE]with the values desired. If, for example a second harddisk with a capacity of 4 GB is mounted under /disk2:

	SQUID_CACHE_1_DIR='/disk2'
	SQUID_CACHE_1_SIZE='3000'

This harddisk would be used only for Squid cache now.

Default Setting is: no additional cache_dir.

[SQUID_NEXT_PROXY]

If the internet access is only possible via a proxy, or for performance reasons an upstream proxy should be accessed, is has to be entered here in the format 'name.domain', eg

	SQUID_NEXT_PROXY='www-proxy.t-online.de'

In case of failure of this proxy Squid tries to resolve the pages directly.

Default Setting is: no upstream proxy

[SQUID_NEXT_PROXY_PORT]

Port of the upstream proxy. Only taken into account if SQUID_NEXT_PROXY is not empty, i.e.

	SQUID_NEXT_PROXY_PORT='80'

Default Setting is: empty
