Domino V12 lets notes.ini hold multiple HTTPAdditionalRespHeader entries

Older Domino releases let you put exactly one HTTPAdditionalRespHeader in notes.ini — a second line silently overwrote the first. HCL added a numbered convention (HTTPAdditionalRespHeader01, 02, …) in V12.0.x so you can ship a full security-header baseline through notes.ini alone, which is the only path that still works when HTTP won't start and the Internet Site documents are unreachable.

Getting Started with NotesQueryResultsProcessor: Life After DQL

NQRP is a LotusScript class added in Domino V12 that lets you re-sort, categorise, project, and serialise the results of a DQL query (or any NotesDocumentCollection) — straight to JSON or to a temporary view. Walks through the create flow, every method signature, the official examples, and the safety knobs.

Getting Started with DQL: Query Notes Documents with SQL-Style Syntax

Domino Query Language (DQL) gives you a near-SQL syntax for querying Notes documents directly, without designing a new view for every query shape. This is Part 1 of the 'DQL Trilogy': DQL's design rationale, writing your first query, calling DQL from LotusScript / Java / REST API, and a syntax cheat sheet. Query-writing pitfalls are in Part 2; shipping to production (catalog maintenance and permissions) is in Part 3.
