# Reload

> Reload the active tab, optionally bypassing the HTTP cache.

## Overview

The `/browser/sessions/{id}/reload` endpoint reloads the currently active tab. By default the reload reuses the HTTP cache; pass `ignoreCache: true` to force a full re-fetch of all resources.

The call blocks until the configured wait condition is met or the timeout elapses.

## Path Parameters

<ParamField path="id" type="string" required={true}>
  Browser session ID (UUID). Create via `POST /browser/sessions`.
</ParamField>

## Body

All body fields are optional — the request body may be omitted entirely.

<ParamField body="ignoreCache" type="boolean" default="false">
  When `true`, bypasses the HTTP cache (equivalent to `Ctrl+Shift+R`). Re-fetches all resources from origin.
</ParamField>

<ParamField body="waitUntil" type="string" default="load">
  When to consider the reload finished. One of `load`, `domcontentloaded`, `networkidle`.
</ParamField>

<ParamField body="timeout" type="integer" default="30000">
  Maximum time (ms) to wait for the reload to complete. Range `0`–`120000`.
</ParamField>

### Error Responses

| Status | Description                                       |
| ------ | ------------------------------------------------- |
| `401`  | Unauthorized — invalid or missing API key.        |
| `404`  | Session not found or not owned by the caller.     |
| `408`  | Reload did not complete before `timeout` elapsed. |
| `503`  | The browser session is temporarily unreachable.   |

## Notes

* `ignoreCache: true` is equivalent to `Ctrl+Shift+R` — re-fetches all resources bypassing the HTTP cache.
* The URL of the active tab is preserved across reloads; only the document and its subresources are refetched.
