HTMX Engine Server
TsgcHTMX_Engine_Server — handles htmx partial-page swap requests over HTTP and broadcasts live out-of-band fragments to all connected browsers over WebSocket.
TsgcHTMX_Engine_Server — handles htmx partial-page swap requests over HTTP and broadcasts live out-of-band fragments to all connected browsers over WebSocket.
Bridges htmx's HTTP-driven partial updates with WebSocket server-push. Incoming htmx requests are dispatched to OnHTMXRequest; your handler returns only the fragment to swap in. Call BroadcastFragment at any time to push live out-of-band updates to every connected browser.
TsgcHTMX_Engine_Server
htmx swaps + live server push
Delphi, C++ Builder, .NET
Wire the engine to your WebSocket server, handle partial-swap requests in OnHTMXRequest, and call BroadcastFragment to push updates to every connected browser.

The TsgcWSHTTPServer this engine attaches to; handles both HTTP partial-swap requests and WebSocket push.
Event fired for every htmx-triggered HTTP request; your handler returns just the fragment HTML to swap in.
Sends an out-of-band htmx payload to every currently connected WebSocket client simultaneously.
Called by the host server for each request; identifies htmx headers and routes to OnHTMXRequest or falls through.
htmx's out-of-band swap attribute: the fragment id must match the target element id on the page.
BroadcastFragment is thread-safe; call it from background timers, push threads or event handlers without locking.
