Header Via

As an intermediary between a client and a back end server, Tempesta FW adds HTTP Via: header field to each message.

hdr_via <string>: sets the value of the header field, not including the mandatory HTTP protocol version number. Note that the value should be a single token. Multiple tokens can be specified in apostrophes, however everything after the first token and a white space will be considered as Via: header field comment. If no value is specified in the directive, the default value is used.
Defaults: tempesta_fw (${tempesta_fw_version})
Example:

hdr_via "private_server";
