Add a dynamic header in packager about iso-8583-socket-queue HOT 4 CLOSED

Hi. You need to use headerFormat parameter to set up the header.

If all of your header values are static, except length, you may set it like so:
--headerFormat=length:n:4,data:an:9:206000000

or you can add extra parameter mode (for the 000 and * thing):
--headerFormat=length:n:4,data:an:9:206000000,mode:an:9

In the second case you need to add mode method that will return the header value in this section:

Looks like this heavy header is set by an upstream not by the client host. Looks really strange.

For this case it takes an option to pass the raw part of client headers as JSON, but there is no such a feature implemented yet.
