Proxy for PubMed

It is not possible to set up a proxy connection in the program itself. That is, you should configure it either through the regular settings of Windows, or by using third-party utilities to forward traffic (e.g., through ProxyCap).

The main scenarios for using a proxy server: bypassing blocking, hiding the real IP, protection of confidential data when connecting to public WiFi access points, interaction with blocked applications, connection to closed portals, forums (which operate only in one country, region).

Selenium WebDriver does not directly create an Internet Explorer (IE) session but instead launches the IE browser. This is because WebDriver is designed to interact with the browser through its WebDriver API, which is different from the native browser session.

When you use Selenium WebDriver with Internet Explorer, it starts the IE browser in a new window, and then you can interact with the browser using the WebDriver API. This allows you to perform actions like navigating to a web page, finding elements, and interacting with them.

It's important to note that Internet Explorer is no longer recommended for use in production environments, and Microsoft has discontinued its development. Microsoft recommends using Microsoft Edge as a more modern and secure alternative. If you need to use Edge with Selenium, you can follow the same approach as with Internet Explorer, using the ChromeDriverService and ChromeOptions classes.

To wait for a button to be clickable using Selenium, you can use the WebDriverWait class along with the expected_conditions module. Here's an example using Python:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Set the path to the ChromeDriver executable
chrome_driver_path = "path/to/chromedriver"

# Initialize the Chrome WebDriver
driver = webdriver.Chrome(executable_path=chrome_driver_path)

# Your Selenium code goes here

# Wait for the button to be clickable
button = WebDriverWait(driver, 10).until(
    EC.element_to_be_clickable((By.ID, "button-id"))
)

# Click the button
button.click()

# Your code after clicking the button

# Close the browser
driver.quit()

Replace path/to/chromedriver with the appropriate path to your ChromeDriver executable and "button-id" with the ID of the button you want to wait for.

In this example, WebDriverWait will wait for up to 10 seconds for the button with the specified ID to become clickable. If the button is not clickable within the specified time, a TimeoutException will be raised.

You can also use other expected_conditions such as visibility_of_element_located, presence_of_element_located, or staleness_of depending on your specific use case.

Open "Options" and then, under "Network", click on "Network Proxy". Now enter in the appropriate fields the IP address of the proxy and its port, based on the type of your proxy: HTTP/HTTPS or SOCKS. In case you suddenly need authorization, enter the authorization data in the appropriate field of the IP address.
