# Sessão

Se você quiser usar o mesmo proxy para fazer várias requisições, você pode adicionar o `X-Oxylabs-Session-Id` header com uma string gerada aleatoriamente ao ID da sessão. Nós atribuiremos um proxy individual a este ID e o usaremos em todas as requisições seguintes por até 10 minutos. Depois disso, atribuiremos um novo proxy a esse ID de sessão específico.

{% hint style="info" %}
Para um desbloqueio de site ideal, Web Unblocker usa sessões predefinidas. Por favor, **evite enviar quaisquer parâmetros personalizados comumente usados para desbloqueio**, pois eles podem interferir na capacidade do Web Unblocker de obter dados de qualidade.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://developers.oxylabs.io/products/pt-br/web-unblocker/making-requests/session.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
