# Save a web context remotely

Persist a web context to the remote WCF service on cross-application navigation. Trigger: OP-07 (navigate between applications and views) step 3 (cross-application navigation).

| Field | Value |
| --- | --- |
| **Operation ID** | OP-06 |
| **Trigger** | OP-07 (navigate between applications and views) step 3 (cross-application navigation) |
| **Inputs** | `applicationName`, `sessionId`, `context` |
| **Outputs** | Remote persistence; no return value |
| **Primary components** | `WebContextService.Save(string applicationName, string sessionId, IWebContext context)` |
| **Entry point** | `src/Web/WebContextService.cs` |

## Steps

1. `Enforce.ArgumentNotNullOrEmpty(applicationName)`, `Enforce.ArgumentNotNullOrEmpty(sessionId)`, `Enforce.ArgumentNotNull(context)` ([BR-01](../business-rules.md#br-01-guarded-arguments-reject-null-or-empty-input)).
2. Open a `WebContextServiceClient` (`using`) and call `Channel.Save(applicationName, sessionId, context)`.**
3. No session-cache write occurs on save.

## Process flow

## Failure and edge-case behavior

- No unexpected failure paths beyond argument-guard exceptions and delegated dependency behavior were identified for this operation.
