-| Range Request Handling | (experimental) How to
treat range requests:
|
-| |
|
-| | - 0 Do not cache (ranges
requested from files taht are already cached due to a non range request will be
a HIT)
|
-| | - 1 Use the
`background_fetch

-| Query String Handling | How to treat query
strings:
|
-| |
|
-| | - 0 use in cache key and
hand up to origin -this means each unique query string Is treated as a unique
URL.
|
-| | - 1 Do not use in cache
key, but pass up to origin - this means a 2 URLs that are the same except for
the query string will match, and cache HIT, while the origin still sees
original query string in the request. |
-| | - 2 Drop at edge - this
means a 2 URLs that are the same except for the query string will match, and
cache HIT, while the origin will not see original query string in the request.
|
-| |
|
-| | **Note:** Choosing to
drop query strings at the edge will preclude the use of a Regex Remap
Expression. See :ref:`rl-regex-remap`.
|

without the use of regex remap, or for further options, see
:ref:`rl-qstring-handling`.

-| Maximum Bytes per Second allowed per session | The maximum bytes per
second a cache will delivery on any single TCP connection. This uses the Linux
kernel's Fair Queuing setsockopt(SO_MAX_PACING_RATE) to limit the rate of
delivery. Traffic exceeding this |
-| | speed will only be
rate-limited and not diverted. This option *requires* `net.core.default_qdisc =
fq` in `/etc/sysctl.conf`.

will be diverted to the bypass destination. For a DNS delivery service, the
Bypass Ipv4 or Ipv6 will be used |

this was a A or AAAA request), and for HTTP delivery services the Bypass FQDN
will be used.
