Giga Allince Proxy

It means organizing a connection through several VPN-servers at once. It is used to protect confidential data as much as possible or to hide one's real IP address. This principle of connection is used, for example, in the TOR-browser. That is, when all traffic is sent immediately through a chain of proxy servers.

To obtain an OAuth2 access token for an unknown service, you will need to follow these general steps. Keep in mind that the exact process may vary depending on the service provider and their OAuth2 implementation.

1. Identify the service provider: Determine the service provider you want to access using OAuth2. This could be a third-party application or API.

2. Check the service provider's documentation: Visit the service provider's official documentation or developer portal to find information about their OAuth2 implementation, including the authorization endpoint, token endpoint, and any required scopes or parameters.

3. Register your application: In most cases, you will need to register your application with the service provider to obtain a client ID and client secret. This is usually done through a dedicated developer portal or console. During registration, you may need to provide information about your application, such as its name, description, and redirect URIs.

4. Obtain authorization code: Direct the user to the service provider's authorization endpoint with the necessary parameters, such as the client ID, client secret, and the desired scopes. The user will be prompted to log in and grant your application access to the requested permissions. Upon successful authentication, the service provider will redirect the user to your application's redirect URI with an authorization code in the URL.

5. Exchange authorization code for an access token: Use your application's backend server to make a POST request to the service provider's token endpoint with the following parameters: client ID, client secret, authorization code, redirect URI, and (optionally) a grant type (usually "authorization_code"). The service provider will respond with an access token, which can be used to authenticate requests to their API on behalf of the user.

6. Store and use the access token: Save the access token securely in your application or cache, and use it in the Authorization header of your API requests to the service provider. Access tokens typically have an expiration time, so you may need to periodically refresh them using a refresh token or by repeating the authorization flow.

Scrapy does support multiple cookies in requests. If you're facing issues:

- Ensure correct cookie syntax (cookies parameter in Request).
- Check for unique cookie names; conflicts may occur.
- Verify cookies match the request domain and path.
- Check cookie expiry dates.
- Some websites may filter or reject requests with multiple cookies.
- Manage sessions and middleware carefully.
- Enable Scrapy logging at DEBUG level for more details.
- Use Scrapy's CookieJar for managing cookies.

This depends directly on how the proxy server works. Some of them do not require any authorization at all, others require username and password for access, and others require you to view ads and so on. Which option will be used depends directly on the service that provides access to the proxy server.

Open the "Browser Properties" in the control panel, in the "Connections" section of the opened window select "Network Settings". Remove the check mark from the "Use proxy" item, click "OK".
