Previously you could pass a single extra HTTP header which was good enough to pass a Gov-Test-Scenario header. However I noticed an endpoint actually allowing another header to be set.

10 headers should be plenty (for now).

Pull request overview

This PR extends mtd-cli to support sending multiple user-supplied extra HTTP headers (up to 10) via the MTD_CLI_HDRS environment variable, instead of only supporting a single header.

Changes:

  • Add parsing of MTD_CLI_HDRS into an array of up to 10 headers (using \ as the separator) and pass that array into libmtdac via mtd_cfg.extra_hdrs.
  • Improve cleanup/exit flow in main() by avoiding early exit() on init failure and freeing allocated header storage on exit paths.
  • Update README documentation to describe how to provide multiple headers.
