SecureAndProxyClient

SecureAndProxyClient

This SDK-style net472 console project demonstrates client-side settings for websocket-sharp without opening a connection by default. Run it with no arguments to print usage and exit.

The example covers:

• SslConfiguration.ServerCertificateValidationCallback for wss:// clients. The default accepts only platform-valid certificates. --allow-local-dev-cert is an explicit exception for localhost or loopback development endpoints and only allows certificate chain errors. --trusted-thumbprint pins a specific server certificate thumbprint when a development endpoint has a non-standard certificate name.
• SetProxy with optional proxy credentials.
• Compression via CompressionMethod.Deflate, with --no-compression to disable the request.
• ConnectionTimeout.
• Bounded opt-in redirects with EnableRedirection and MaxRedirections (0..100, default 5). Cross-origin redirects omit HTTP credentials, cookies, user headers, and TLS client certificates, including reconnects. Secure wss:// to insecure ws:// downgrade remains blocked unless --allow-insecure-redirect is supplied explicitly.
• Origin and SetUserHeader.
