# Parallels Web Client and User Portal

Parallels Web Client is a client application that runs in a web browser. Users can use Parallels Web Client to access User Portal that allows to view and launch remote applications and desktop from a web browser.

Compared to platform-specific Parallels Clients (Parallels Client for Windows, Parallels Client for iOS, etc.), Parallels Web Client does not require end users to install additional software on their computers or mobile devices. Feature-wise, platform-specific Parallels Clients give users more options than Parallels Web Client. Nonetheless, Parallels Web Client is a fully-featured platform-independent client providing end users with an alternative method of working with remote resources published via Parallels RAS.

## **System requirements**

Secure Gateway (hosts the User Portal and Web Client):

* Windows Server 2012 R2 or higher.

Client side:

* Any HTML5-enabled web browser, except Internet Explorer.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.parallels.com/landing/ras-admin-guide/parallels-ras-21-administrators-guide/parallels-web-client-and-user-portal.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
