[PR] [backport camel-4.14.x] CAMEL-23588: camel-undertow - filter the legacy websocket.* exchange-header prefix [camel]
oscerd opened a new pull request, #23993:
URL: https://github.com/apache/camel/pull/23993
Backport to `camel-4.14.x` of CAMEL-23588 (main commit `d5a717dd0f8`).
## Note: adapted, not a verbatim backport
On `camel-4.14.x`, `UndertowHeaderFilterStrategy` is the **`@deprecated`** implementation extending `DefaultHeaderFilterStrategy` (on main / 4.18.x it was rewritten to extend `HttpHeaderFilterStrategy`). A verbatim cherry-pick is therefore impossible. The change is adapted to 4.14.x's structure: the existing `initialize()` now adds the legacy `websocket.` prefix to the in/out filter prefixes (alongside `Camel` / `camel`).
The `DefaultHeaderFilterStrategy.doFiltering` `lowerCase` fallback matches the prefix case-insensitively, so `websocket.*` headers (in any case) are filtered in both directions — behaviour equivalent to main.
## Changes
- `UndertowHeaderFilterStrategy`: add `WEBSOCKET_FILTER_STARTS_WITH = "websocket."` and include it in `setOutFilterStartsWith` / `setInFilterStartsWith`.
- `camel-4x-upgrade-guide-4_14.adoc`: add the `camel-undertow` "potential breaking change" entry, grouped with the existing `camel-vertx-websocket` / `camel-atmosphere-websocket` (CAMEL-23532) family.
The matching entry will be synced to the `4_14` upgrade guide on `main` in a separate doc-sync PR, per the upgrade-guide policy.
