## PostLogoutRedirectUrisValidator Class

Verifies that the request's `post_logout_redirect_uri` is one of the URIs the
resolved client previously registered \(OpenID Connect RP\-Initiated Logout 1\.0 §2\)\.
A request without `post_logout_redirect_uri` is allowed; if one is present but
the client cannot be resolved from `client_id` or `id_token_hint`, the
redirect URI cannot be safely validated and the request is rejected\.

```csharp
public class PostLogoutRedirectUrisValidator : Abblix.Oidc.Server.Endpoints.EndSession.Validation.IEndSessionContextValidator
```

### Methods

## PostLogoutRedirectUrisValidator\.ValidateAsync\(EndSessionValidationContext\) Method {#Abblix.Oidc.Server.Endpoints.EndSession.Validation.PostLogoutRedirectUrisValidator.ValidateAsync(Abblix.Oidc.Server.Endpoints.EndSession.Validation.EndSessionValidationContext)}

Performs this validator's check against the shared context\.

```csharp
public System.Threading.Tasks.Task<Abblix.Oidc.Server.Common.OidcError?> ValidateAsync(Abblix.Oidc.Server.Endpoints.EndSession.Validation.EndSessionValidationContext context);
```
#### Parameters

###### `context` [EndSessionValidationContext](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.EndSession.Validation.EndSessionValidationContext 'Abblix\.Oidc\.Server\.Endpoints\.EndSession\.Validation\.EndSessionValidationContext') {#Abblix.Oidc.Server.Endpoints.EndSession.Validation.PostLogoutRedirectUrisValidator.ValidateAsync(Abblix.Oidc.Server.Endpoints.EndSession.Validation.EndSessionValidationContext).context}

Mutable validation context shared with subsequent steps; this validator may
populate fields \(such as resolved `ClientInfo` or parsed `id_token_hint`\)\.
