This is documentation about a configuration directive, which can be placed within Movable Type’s core configuration file, mt-config.cgi, to customize the behavior of the system.

The SearchThrottleIPWhitelist configuration directive allows you to create a bypass mechanism (whitelist) for the IP-address-based search throttle.

You can specify one or more addresses on the same line. Multiple addresses can be separated by space, a semi-colon, or a comma.

Partial IP addresses are acceptable to allow bypass of IP blocks. Exact match from beginning of IP address

Any search from a matching IP address is allowed with no throttle control applied. If no match, the normal throttle test (using ThrottleSeconds) is executed.


The following translates to all IPs in the 64.232.18.* block:

SearchThrottleIPWhitelist 64.232.18.

The following translates allows throttle bypass for 10...*:

SearchThrottleIPWhitelist 10.

The following (same as above but without the period):

SearchThrottleIPWhitelist 10

…is equivalent to the following:

SearchThrottleIPWhitelist 100 101 102 103 104 105 106 107 108 109
