# Portals

You can use portals to move from Session to Session, without the need to go back to the main menu. For more information about portals, see [Travelling through a portal](/engage/essential-features/travelling-through-a-portal.md).

If you add a portal to an experience, and a user travels through it, they will leave your experience. If the user want to access your experience again, they may need to reload it and start at the beginning.

## Portal effect options

For instructions on how to access effect options, see [Effect options](/engage/experience-editor/working-with-objects/effect-options.md). For a portal IFX, the effect options provide access to set the target Session ID. This is the ID for the persistent Session that the portal will lead to. For information about how to find a Session ID, see [Finding a Session ID](/engage/sessions/finding-a-session-id.md).

## 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, and the optional `goal` query parameter:

```
GET https://docs.engagevr.io/engage/experience-editor/working-with-objects/ifx/portals.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
