# VLESS-GRPC ## Schematic (Caddy): Xray client <--- gRPC(TLS) ---> Caddy2 <--- gRPC(cleartext) ---> Xray server ## Nginx: At the same time, you can also choose to use Nginx. A sample configuration snippet is as follows (partially from [@xqzr](https://github.com/xqzr)): ```conf server { listen 443 ssl http2 so_keepalive=on; server_name example.com; index index.html; root /var/www/html; ssl_certificate /path/to/example.cer; ssl_certificate_key /path/to/example.key; ssl_protocols TLSv1.2 TLSv1.3; ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE -RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384; client_header_timeout 52w; keepalive_timeout 52w; # Fill in /your ServiceName after location location /your ServiceName { if ($content_type !~ "application/grpc") { return 404; } client_max_body_size 0; client_body_buffer_size 512k; grpc_set_header X-Real-IP $remote_addr; client_body_timeout 52w; grpc_read_timeout 52w; grpc_pass unix:/dev/shm/Xray-VLESS-gRPC.socket; } } ```
