Description
===========

Some of the values that are set in :file:`records.config` can be changed for a
specific transaction. It is important to note that these functions change the
configuration values stored for the transaction, which is not quite the same as
changing the actual operating values of the transaction. The critical effect is
the value must be changed before it is used by the transaction - after that,
changes will not have any effect.

All of the ``...Get`` functions store the internal value in the storage
indicated by the :arg:`value` argument. For strings :arg:`length*` will receive
the length of the string.

The values are identified by the enumeration :enum:`TSOverridableConfigKey`.
String values can be used indirectly by first passing them to
:func:`TSHttpTxnConfigFind` which, if the string matches an overridable value,
return the key and data type.

Configurations
==============

Testing :enumerator:`TS_CONFIG_BODY_FACTORY_TEMPLATE_BASE`.

The following configurations (from ``records.config``) are overridable:
