Cisco HTTP Proxy

In a local network, you will need two computers to do this. One will be used as a proxy server, the other as a client. Then you need to activate the proxy on the server. And on the client PC - choose to access the Internet via a local network connection (i.e. from the server). Another option is to use a web server like Nginx.

If you have a legitimate use case and need to interact with YouTube data, consider using the YouTube Data API in compliance with YouTube's terms of service. The API allows you to retrieve information about videos, playlists, channels, and comments, but it has specific rules and limitations.

Before using any API, make sure to:

1. Review API Documentation: Understand the features, limitations, and terms of use of the YouTube Data API.

2. Obtain API Key or OAuth Token: To use the YouTube Data API, you need to obtain an API key or use OAuth 2.0 authentication.

3. Comply with YouTube's Policies: Follow YouTube's terms of service and community guidelines. Unauthorized actions, spamming, or any form of abuse can result in penalties.

Here's a basic example using the YouTube Data API (in Python with the google-api-python-client library):

from googleapiclient.discovery import build

# Replace with your API key or use OAuth 2.0 authentication
api_key = 'your_api_key'
youtube = build('youtube', 'v3', developerKey=api_key)

# Example: Retrieving comments from a video
video_id = 'your_video_id'
comments = youtube.commentThreads().list(part='snippet', videoId=video_id).execute()

# Process comments as needed
for comment in comments['items']:
    snippet = comment['snippet']['topLevelComment']['snippet']
    author = snippet['authorDisplayName']
    text = snippet['textDisplay']
    print(f"{author}: {text}")

Note: This example retrieves comments from a video, but posting comments is not supported in the current version of the API.

If you want to access Instagram data, consider using the Instagram Graph API. However, note that the Graph API has limitations and may not provide access to all public content.

Here is an example using Python and the instagram_private_api library

from instagram_private_api import Client, ClientCompatPatch

# Replace 'your_username' and 'your_password' with your Instagram credentials
username = 'your_username'
password = 'your_password'

api = Client(username, password)
results = api.user_feed('instagram', count=10)  # Replace 'instagram' with the target account username

for post in results['items']:
    media_id = post['id']
    comments = api.media_n_comments(media_id, count=5)  # Replace 5 with the desired number of comments to retrieve
    for comment in comments['comments']:
        print(comment['user']['username'] + ': ' + comment['text'])

api.logout()

To connect to a proxy server with a password, provide the proxy address, port, and authentication credentials (username and password) in your browser or application settings. For popular browsers like Google Chrome and Mozilla Firefox, follow these general steps:

Open the browser and go to its settings.
Locate the proxy settings section.
Enter the proxy server address, port, username, and password.
Save the settings.

In data centers, proxies are used to provide IP to virtual servers. After all, one server there can be used by a dozen users at the same time. And each needs to be allocated its own IP and port. All this is done through proxies.
