Reverse Proxy Mac

Each option has its own advantages and disadvantages. HTTP is faster because it supports caching. And SOCKS provides better anonymity because it hides the headers of requested pages.

And it depends on what purpose the proxy is used for. But you should definitely give preference to paid proxies. They are more reliable, always available, and with that comes a guarantee of privacy. Unfortunately, personal data is often stolen from free proxies.

In Selenium, you can check if the DOM of a page is loaded by using JavaScriptExecutor. Here's how you can check:

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("http://www.example.com")

while True:
    try:
        driver.execute_script("return document.readyState")
        if driver.execute_script("return document.readyState") == "complete":
            print("Page is loaded")
            break
    except Exception as e:
        print("Exception occurred")

In this script, the document.readyState property is used to check if the page is loaded or not. In JavaScript, the "complete" value of document.readyState indicates that the page is loaded.

This script will keep running until the page is loaded. Once the page is loaded, it will print "Page is loaded" and break the loop.

Please note that this script assumes that the page is completely loaded when document.readyState is "complete". However, this is not always the case. Sometimes, some elements may still be loading even when document.readyState is "complete". So, it's better to use explicit or implicit waits to wait for specific elements to be present or visible.

A proxy for Instagram refers to a service or tool that acts as an intermediary between your device and the Instagram platform. It is used to hide your IP address, bypass geographical restrictions, or automate certain tasks such as liking, commenting, or following. There are several reasons why someone might use a proxy for Instagram:

1. Privacy and anonymity: By using a proxy, your real IP address is hidden, making it more difficult for Instagram or other users to track your online activities. This can be useful for maintaining privacy or avoiding potential harassment or stalking.

2. Bypassing geographical restrictions: Some Instagram features or content may be restricted based on your location. A proxy can help you bypass these restrictions by routing your traffic through a server in a different country, allowing you to access content that would otherwise be unavailable.

3. Automation: Proxies can be used to automate tasks on Instagram, such as liking, commenting, or following multiple accounts in a short period. This can save time and effort, but it's important to note that using bots or automation tools in violation of Instagram's terms of service can result in the suspension or permanent ban of your account.

4. Security: Using a proxy can provide an additional layer of security by acting as a buffer between your device and the Instagram platform. This can help protect your account from potential hacking or unauthorized access.

If you can't proxy requests in Scrapy:

- Verify correct proxy configuration in Scrapy settings.
- Confirm proxy functionality with external tools.
- Check for typos or errors in your code and settings.
- Ensure proxy authentication details are correct.
- Test with a direct internet connection to isolate the issue.
- Check for IP blocking by the target website.
- Confirm proper configuration of the HttpProxyMiddleware.
- Use Scrapy logging to inspect requests and responses.
- Ensure your proxy supports HTTPS if needed.
- Test with a single, static proxy for simplicity.
- Keep Scrapy and dependencies up to date.
- Consider using middleware libraries like scrapy-rotating-proxies.
