Mmsc Proxy

If Selenium is having trouble connecting to a proxy, there are several steps you can take to troubleshoot and resolve the issue. Here are some common solutions:

1. Check Proxy Configuration:

   • Verify that the proxy settings you are using are correct. Double-check the proxy address, port, and any authentication credentials if required.

2. Use the Correct WebDriver for the Browser:

   • Ensure that you are using the correct WebDriver executable for the browser you are automating. For example, if you are using Chrome, make sure you have the correct version of ChromeDriver.

3. Specify Proxy Settings in WebDriver Options:

   • When creating a WebDriver instance, make sure to set the proxy settings in the WebDriver options. Here's an example for Chrome:

from selenium import webdriver

proxy_address = "your_proxy_address"
proxy_port = "your_proxy_port"

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f'--proxy-server=http://{proxy_address}:{proxy_port}')

driver = webdriver.Chrome(options=chrome_options)

Handle Proxy Authentication:

• If your proxy requires authentication, make sure to provide the username and password in the proxy settings. Adjust the code accordingly:

chrome_options.add_argument(f'--proxy-server=http://username:password@{proxy_address}:{proxy_port}')

5. Check for Firewalls and Security Software:

   • Firewalls or security software on your machine may block the connection to the proxy. Temporarily disable such software to see if it resolves the issue.

6. Test Proxy Connection Outside Selenium:

   • Test whether you can connect to the proxy outside of Selenium using tools like curl or a browser. This helps determine if the issue is specific to Selenium or if there are broader network or proxy configuration issues.

7. Verify Proxy Availability:

   • Ensure that the proxy server is reachable and available. Try connecting to it manually or use network diagnostic tools to check its status.

8. Check Proxy Logs:

   • If the proxy server has logs, check them for any error messages or indications of connection issues. This can provide insights into why the connection is failing.

9. Update Selenium and Browser Drivers:

   • Ensure that you are using the latest version of Selenium WebDriver and browser drivers (e.g., ChromeDriver, GeckoDriver). Update them if needed to address any compatibility issues.

10. Use a Different Proxy:

    • If possible, try using a different proxy server to see if the issue persists. This can help determine whether the problem is specific to the proxy configuration.

11. Browser Specifics:

    • Some browsers may have specific settings or configurations related to proxy usage. Check the browser's documentation for any additional steps required for using a proxy with Selenium.

12. Consider Using a Proxy Service:

    • If you are facing difficulties with a specific proxy server, consider using a proxy service or a different proxy provider to see if it resolves the issue.

By following these steps and adjusting your Selenium code accordingly, you should be able to troubleshoot and resolve most issues related to connecting to a proxy with Selenium.

A NoSuchElementException in Selenium occurs when the WebDriver cannot find an HTML element based on the specified criteria. Common reasons include incorrect locator strategy, element not yet present, incorrect locator value, incomplete page load, element inside an iframe, or WebDriver/browser compatibility issues. Use explicit waits, verify correct locators, ensure elements are present, and handle iframes or shadow DOM appropriately to address this exception.

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.

The basic configuration is written in nginx.conf file in the program directory. You need to create a server article and specify there the port number and the place for cached data. Thus, for example, by using port 8080 you may organize a local proxy to test your own sites.

It means a private proxy server used by several users. For example, one of them has bought a paid proxy and lets his friend use it for a fee. That is, he "shared" his proxy (shared means "common").
