Module client_headers 

Optional extra HTTP headers for outbound RPC and WebSocket clients (WAF / reverse proxy).

Functions

header_map_from_lines

Build a map from independent lines (config file array entries, each Name: value).

header_map_redacted_summary

Comma-separated summary for logs — sensitive header values redacted.

merge_header_line

Parse Name: value and insert into the map (replaces an existing same name).

merge_into

Merge into into_map: each pair from source is inserted (same name replaced).

parse_header_line

Split Name: value on the first colon (value may contain further colons).

parse_tb_headers_env

Parse TB_HEADERS: one Name: value per line (\n or \r\n). Empty lines and # comments skipped. Commas inside values are fine; newlines inside a value are not supported (use another line for another header).
