## AuthorizationRequestStorage Class

Provides storage and retrieval services for OAuth 2\.0 authorization requests using a distributed cache\.
This class is designed to handle the storage of [AuthorizationRequest](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Model.AuthorizationRequest 'Abblix\.Oidc\.Server\.Model\.AuthorizationRequest') objects and facilitate
their retrieval using unique request URIs, supporting scenarios such as the OAuth 2\.0 Pushed Authorization Requests
\(PAR\)\.

```csharp
public class AuthorizationRequestStorage : Abblix.Oidc.Server.Features.Storages.IAuthorizationRequestStorage

### Methods

## AuthorizationRequestStorage\.StoreAsync\(AuthorizationRequest, TimeSpan\) Method {#Abblix.Oidc.Server.Features.Storages.AuthorizationRequestStorage.StoreAsync(Abblix.Oidc.Server.Model.AuthorizationRequest,System.TimeSpan)}

Stores an authorization request in the distributed cache with a generated URI and a specified expiration time\.

```csharp
public System.Threading.Tasks.Task<Abblix.Oidc.Server.Endpoints.PushedAuthorization.Interfaces.PushedAuthorizationResponse> StoreAsync(Abblix.Oidc.Server.Model.AuthorizationRequest request, System.TimeSpan expiresIn);
```
#### Parameters

###### `request` [AuthorizationRequest](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Model.AuthorizationRequest 'Abblix\.Oidc\.Server\.Model\.AuthorizationRequest') {#Abblix.Oidc.Server.Features.Storages.AuthorizationRequestStorage.StoreAsync(Abblix.Oidc.Server.Model.AuthorizationRequest,System.TimeSpan).request}

The authorization request to store\.

###### `expiresIn` [System\.TimeSpan](https://learn.microsoft.com/en-us/dotnet/api/system.timespan 'System\.TimeSpan') {#Abblix.Oidc.Server.Features.Storages.AuthorizationRequestStorage.StoreAsync(Abblix.Oidc.Server.Model.AuthorizationRequest,System.TimeSpan).expiresIn}

The duration after which the stored request will expire and no longer be valid\. This
            duration is typically dictated by the OAuth 2\.0 server's configuration and the nature of the client's request\.

Implements [StoreAsync\(AuthorizationRequest, TimeSpan\)](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.Storages.IAuthorizationRequestStorage#Abblix.Oidc.Server.Features.Storages.IAuthorizationRequestStorage.StoreAsync(Abblix.Oidc.Server.Model.AuthorizationRequest,System.TimeSpan) 'Abblix\.Oidc\.Server\.Features\.Storages\.IAuthorizationRequestStorage\.StoreAsync\(Abblix\.Oidc\.Server\.Model\.AuthorizationRequest, System\.TimeSpan\)')

Whether to remove the request from the cache after retrieving it\. This is typically
            true for operations where the request is intended for single retrieval, such as after redirecting a client
            to an authorization endpoint\.

Implements [TryGetAsync\(Uri, bool\)](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.Storages.IAuthorizationRequestStorage#Abblix.Oidc.Server.Features.Storages.IAuthorizationRequestStorage.TryGetAsync(System.Uri,bool) 'Abblix\.Oidc\.Server\.Features\.Storages\.IAuthorizationRequestStorage\.TryGetAsync\(System\.Uri, bool\)')
