isConnectionHeader back to summary

isConnectionHeader	back to summary
public static boolean isConnectionHeader(CharSequence name, boolean ignoreTeHeader) Check if a header name is "connection related". The RFC9110 only specify an incomplete list of the following headers: `Connection` `Proxy-Connection` `Keep-Alive` `TE` `Transfer-Encoding` `Upgrade` Parameters name:CharSequence the name of the header to check. The check is case-insensitive. ignoreTeHeader:boolean `true` if the `TE` header should be ignored by this check. This is relevant for HTTP/2 header validation, where the `TE` header has special rules. Returns:boolean `true` if the given header name is one of the specified connection-related headers.

Upgrade

Parameters

name:CharSequence: the name of the header to check. The check is case-insensitive.
ignoreTeHeader:boolean: true if the TE header should be ignored by this check. This is relevant for HTTP/2 header validation, where the TE header has special rules.
