## Topics

### Creating Proxy Configurations

[`nw_proxy_config_create_relay(_:_:)`](/documentation/Network/nw_proxy_config_create_relay(_:_:))

Initializes a proxy configuration with one or two relay hops.

[`nw_relay_hop_t`](/documentation/Network/nw_relay_hop_t)

A single relay server you can chain together with other servers.

[`nw_proxy_config_create_oblivious_http(_:_:_:_:)`](/documentation/Network/nw_proxy_config_create_oblivious_http(_:_:_:_:))

Initializes an Oblivious HTTP proxy configuration using a relay and a gateway.

[`nw_proxy_config_create_http_connect(_:_:)`](/documentation/Network/nw_proxy_config_create_http_connect(_:_:))

Initializes a legacy HTTP CONNECT configuration for a proxy server accessible using HTTP/1.1.

[`nw_proxy_config_create_socksv5(_:)`](/documentation/Network/nw_proxy_config_create_socksv5(_:))

Initializes a SOCKSv5 proxy configuration.

### Customizing Proxy Behavior

[`nw_proxy_config_set_failover_allowed(_:_:)`](/documentation/Network/nw_proxy_config_set_failover_allowed(_:_:))

Configures whether or not a proxy configuration allows failover to non-proxied connections. Failover isn’t allowed by default.

[`nw_proxy_config_set_username_and_password(_:_:_:)`](/documentation/Network/nw_proxy_config_set_username_and_password(_:_:_:))

Sets a username and password to use as authentication for a proxy configuration.

### Inspecting Proxies

[`nw_proxy_config_get_failover_allowed(_:)`](/documentation/Network/nw_proxy_config_get_failover_allowed(_:))

Checks if a proxy configuration allows failover to non-proxied connections.
