Re: [squid-users] Questions about Squid read_timeout and retry behavior

Hello Katie,

Check the "retry_on_error" in squid.conf file.

If set to on Squid will automatically retry requests when
receiving an error response. This is mainly useful if you
are in a complex cache hierarchy to work around access
control errors.

Thanks,
