VLESS XHTTP

This is a family of "VLESS over a transport" nodes on Xray. The HTTP-based transports (XHTTP, WebSocket, gRPC, HTTPUpgrade) can pass through a CDN, so a node stays usable through the CDN after the VPS's IP is blocked.

Cores	Xray
Domain and certificate	needed by most modes; not by the REALITY layer or mKCP
Shared port 443	yes for the TLS modes (--mount-443); not for mKCP
Common clients	recent Xray-based clients such as v2rayN and v2rayNG

Seven modes

--mode	Name in the menu	Domain and certificate	Notes
xhttp	XHTTP/SplitHTTP	needed	Xray's newest HTTP transport; works through a CDN
ws	WebSocket	needed	the most compatible; works through a CDN
grpc	gRPC	needed	multiplexed; works through a CDN
httpupgrade	HTTPUpgrade	needed	one framing layer less than WebSocket
h2	HTTP/2	needed	carried by XHTTP stream-one (Xray removed its old HTTP transport)
reality-layer	Reality layer	not needed	REALITY camouflage, with --reality-transport xhttp|grpc
mkcp	mKCP	not needed	UDP without TLS, disguised by a seed and header; copes with loss but uses noticeably more traffic

For the modes that need a domain, prepare the certificate as for Vision: point the domain at the VPS and issue it in main menu 10 (SSL certificates).

From the menu

Main menu 4 → 4 (Nodes) → 3 (XHTTP), then pick the mode.

From the command line

# XHTTP (for WebSocket, gRPC and the rest, use ws, grpc, httpupgrade, h2)
psm node add xray xhttp --tag my-xhttp --port 2087 \
  --domain hk.example.com --mode xhttp

# REALITY layer, no domain needed
psm node add xray xhttp --tag my-xhttp-reality --port 8443 \
  --mode reality-layer --reality-transport xhttp

# mKCP (UDP)
psm node add xray xhttp --tag my-kcp --port 9000 --mode mkcp

For mKCP, --kcp-seed sets the obfuscation seed and --kcp-header the disguise header. It runs over UDP, so it cannot go on shared port 443; be careful on servers billed by traffic.

Export for clients

psm node export xray xhttp my-xhttp
