# Sesión

Si quieres usar el mismo proxy para hacer varias solicitudes, puedes añadir el `X-Oxylabs-Session-Id` encabezado con una cadena generada aleatoriamente al ID de sesión. Asignaremos un proxy individual a este ID y lo usaremos para todas las solicitudes siguientes durante hasta 10 minutos. Después de eso, asignaremos un nuevo proxy a ese ID de sesión en particular.

{% hint style="info" %}
Para un desbloqueo óptimo de sitios web, Web Unblocker usa sesiones predefinidas. Por favor **evita enviar cualquier parámetro personalizado que se use comúnmente para el desbloqueo**, ya que pueden interferir con la capacidad de Web Unblocker para obtener datos de calidad.

# 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/es/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.
