Profile Chains

In general, these are variables of a profile, which are automatically transferred with this prefix to a called subsequent profile. These variables are therefore only available in the subsequent profile, where they are initialised at the start of phase 1. See chapter Passed Variables in section Profile Chains. Please also note the special features for the classes CallCronProfile and CallProfile.

See also section Metadata Editor.

HTTP

However, this prefix is also used for automatically set system variables for HTTP request parameters and HTTP headers. These variables are partly accessible in the same profile, but sometimes only in the subsequent profile.

AMQP

In addition, such variables can also be used to read parameters in headers of AMQP messages. See section AMQP/JMS (Input Agent).
