Usage of these options allows users to access alpha features that are not
available as part of the primary configuration structure for OAuth2 Proxy.
:::warning
The options within this structure are considered alpha.
They may change between releases without notice.
:::
| Field | Type | Description |
| ----- | ---- | ----------- |
| `upstreams` | _[Upstreams](#upstreams)_ | Upstreams is used to configure upstream servers.<br/>Once a user is authenticated, requests to the server will be proxied to<br/>these upstream servers based on the path mappings defined in this list. |
| `injectRequestHeaders` | _[[]Header](#header)_ | InjectRequestHeaders is used to configure headers that should be added<br/>to requests to upstream servers.<br/>Headers may source values from either the authenticated user's session<br/>or from a static secret value. |
| `injectResponseHeaders` | _[[]Header](#header)_ | InjectResponseHeaders is used to configure headers that should be added<br/>to responses from the proxy.<br/>This is typically used when using the proxy as an external authentication<br/>provider in conjunction with another proxy such as NGINX and its<br/>auth_request module.<br/>Headers may source values from either the authenticated user's session<br/>or from a static secret value. |
### ClaimSource
(**Appears on:** [HeaderValue](#headervalue))
ClaimSource allows loading a header value from a claim within the session
| Field | Type | Description |
| ----- | ---- | ----------- |
| `claim` | _string_ | Claim is the name of the claim in the session that the value should be<br/>loaded from. |
| `prefix` | _string_ | Prefix is an optional prefix that will be prepended to the value of the<br/>claim if it is non-empty. |
| `basicAuthPassword` | _[SecretSource](#secretsource)_ | BasicAuthPassword converts this claim into a basic auth header.<br/>Note the value of claim will become the basic auth username and the<br/>basicAuthPassword will be used as the password value. |
### Duration
#### (`string` alias)
(**Appears on:** [Upstream](#upstream))
Duration is as string representation of a period of time.
A duration string is a is a possibly signed sequence of decimal numbers,
each with optional fraction and a unit suffix, such as "300ms", "-1.5h" or "2h45m".
Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
### Header
(**Appears on:** [AlphaOptions](#alphaoptions))
Header represents an individual header that will be added to a request or
response header.
| Field | Type | Description |
| ----- | ---- | ----------- |
| `name` | _string_ | Name is the header name to be used for this set of values.<br/>Names should be unique within a list of Headers. |
| `preserveRequestValue` | _bool_ | PreserveRequestValue determines whether any values for this header<br/>should be preserved for the request to the upstream server.<br/>This option only applies to injected request headers.<br/>Defaults to false (headers that match this header will be stripped). |
| `values` | _[[]HeaderValue](#headervalue)_ | Values contains the desired values for this header |
### HeaderValue
(**Appears on:** [Header](#header))
HeaderValue represents a single header value and the sources that can
make up the header value
| Field | Type | Description |
| ----- | ---- | ----------- |
| `value` | _[]byte_ | Value expects a base64 encoded string value. |
| `fromEnv` | _string_ | FromEnv expects the name of an environment variable. |
| `fromFile` | _string_ | FromFile expects a path to a file containing the secret value. |
| `claim` | _string_ | Claim is the name of the claim in the session that the value should be<br/>loaded from. |
| `prefix` | _string_ | Prefix is an optional prefix that will be prepended to the value of the<br/>claim if it is non-empty. |
| `basicAuthPassword` | _[SecretSource](#secretsource)_ | BasicAuthPassword converts this claim into a basic auth header.<br/>Note the value of claim will become the basic auth username and the<br/>basicAuthPassword will be used as the password value. |
SecretSource references an individual secret value.
Only one source within the struct should be defined at any time.
| Field | Type | Description |
| ----- | ---- | ----------- |
| `value` | _[]byte_ | Value expects a base64 encoded string value. |
| `fromEnv` | _string_ | FromEnv expects the name of an environment variable. |
| `fromFile` | _string_ | FromFile expects a path to a file containing the secret value. |
### Upstream
(**Appears on:** [Upstreams](#upstreams))
Upstream represents the configuration for an upstream server.
Requests will be proxied to this upstream if the path matches the request path.
| Field | Type | Description |
| ----- | ---- | ----------- |
| `id` | _string_ | ID should be a unique identifier for the upstream.<br/>This value is required for all upstreams. |
| `path` | _string_ | Path is used to map requests to the upstream server.<br/>The closest match will take precedence and all Paths must be unique. |
| `uri` | _string_ | The URI of the upstream server. This may be an HTTP(S) server of a File<br/>based URL. It may include a path, in which case all requests will be served<br/>under that path.<br/>Eg:<br/>- http://localhost:8080<br/>- https://service.localhost<br/>- https://service.localhost/path<br/>- file://host/path<br/>If the URI's path is "/base" and the incoming request was for "/dir",<br/>the upstream request will be for "/base/dir". |
| `insecureSkipTLSVerify` | _bool_ | InsecureSkipTLSVerify will skip TLS verification of upstream HTTPS hosts.<br/>This option is insecure and will allow potential Man-In-The-Middle attacks<br/>betweem OAuth2 Proxy and the usptream server.<br/>Defaults to false. |
| `static` | _bool_ | Static will make all requests to this upstream have a static response.<br/>The response will have a body of "Authenticated" and a response code<br/>matching StaticCode.<br/>If StaticCode is not set, the response will return a 200 response. |
| `staticCode` | _int_ | StaticCode determines the response code for the Static response.<br/>This option can only be used with Static enabled. |
| `flushInterval` | _[Duration](#duration)_ | FlushInterval is the period between flushing the response buffer when<br/>streaming response from the upstream.<br/>Defaults to 1 second. |
| `passHostHeader` | _bool_ | PassHostHeader determines whether the request host header should be proxied<br/>to the upstream server.<br/>Defaults to true. |
| `proxyWebSockets` | _bool_ | ProxyWebSockets enables proxying of websockets to upstream servers<br/>Defaults to true. |
### Upstreams
#### ([[]Upstream](#upstream) alias)
(**Appears on:** [AlphaOptions](#alphaoptions))
Upstreams is a collection of definitions for upstream servers.
