Class Http1KeepAlive

java.lang.Object

dev.relism.flash.http1.Http1KeepAlive

public final class Http1KeepAlive
extends Object

HTTP/1.1 keep-alive decision (RFC 9110 §7.6.1) and the shared Connection header token-list scanner both it and WebSocket upgrade detection need. (e.g. "Connection: keep-alive, Upgrade"), not a single value — a whole-value compare against "close" misses exactly that case. tokenListContains(dev.relism.fpr.core.ByteView, java.lang.String) is the one scanner both this class's isKeepAlive(dev.relism.flash.models.Request) and WebSocketUpgrade's Connection: Upgrade check use, so the two can never drift apart again.

Method Summary

Modifier and Type	Method	Description
static boolean	connectionContainsToken(Request request, String token)	Whether the request's Connection header lists token (case-insensitive).
static boolean	isKeepAlive(Request request)	Whether the connection should remain open after this response.
static boolean	tokenEqualsIgnoreCase(dev.relism.fpr.core.ByteView view, int start, int end, String token)	Case-insensitive compare of view[start, end), trimming trailing spaces, against token.
static boolean	tokenListContains(dev.relism.fpr.core.ByteView view, String token)	Scans a comma-separated token list for token (case-insensitive, OWS-tolerant).

Method Details

isKeepAlive

public static boolean isKeepAlive(Request request)

Whether the connection should remain open after this response. HTTP/1.1 defaults to keep-alive unless Connection lists close; HTTP/1.0 defaults to close unless it lists keep-alive.

connectionContainsToken

public static boolean connectionContainsToken(Request request,
 String token)

Whether the request's Connection header lists token (case-insensitive).

tokenListContains

public static boolean tokenListContains(dev.relism.fpr.core.ByteView view,
 String token)

Scans a comma-separated token list for token (case-insensitive, OWS-tolerant).

tokenEqualsIgnoreCase

public static boolean tokenEqualsIgnoreCase(dev.relism.fpr.core.ByteView view,
 int start,
 int end,
 String token)

Case-insensitive compare of view[start, end), trimming trailing spaces, against token.
