Instant Unblock Proxy

In CentOS, if there is no graphical interface (from the terminal), proxy configuration is done through the export http_proxy=http://User:Pass@Proxy:Port/ command. Accordingly, User is the user, Pass is the password to identify you, Proxy is the IP address of the proxy, and Port is the port number. If you have DE, the configuration can be done via Network Manager (as in any other Linux distribution).

In web development, the style.left property refers to the left offset position of an element within its containing element. The value of style.left is a string that represents the distance from the element's left edge to the left edge of its containing element. This distance can be specified using various units, such as pixels, percentages, or other length units.

When you retrieve style.left in JavaScript, you get a string representation of this distance. For example:

var element = document.getElementById('exampleElement');
var leftValue = element.style.left; // Returns a string like "10px" or "50%"

To perform numerical calculations or comparisons with the left offset, you might want to parse this string and extract the numeric value. Parsing involves removing the unit (e.g., "px" or "%") and converting the remaining part to a numeric value.

Here's an example of how you can parse the style.left value in JavaScript:

var element = document.getElementById('exampleElement');
var leftValue = element.style.left;

// Parse the numeric value
var parsedLeft = parseFloat(leftValue);

// Now parsedLeft is a numeric value representing the left offset
console.log(parsedLeft);

By parsing the value, you can use it in mathematical operations or make comparisons. Keep in mind that parsing might return NaN (Not a Number) if the value is not a valid number, so it's important to handle such cases appropriately.

The Simple HTML DOM Parser is a PHP library that allows you to manipulate HTML content easily. Below is an example of how to use the Simple HTML DOM Parser to parse and extract information from an HTML document.

First, make sure you have the Simple HTML DOM Parser library included in your project. You can download it from the official repository on GitHub.

Include the library in your PHP file:

include('path/to/simple_html_dom.php');

Use the library to parse and extract information from an HTML document:

// Example HTML content
$htmlContent = '
Hello, world!
';

// Create a Simple HTML DOM object
$html = str_get_html($htmlContent);

// Extract text content from a specific element
$textContent = $html->find('div.container p', 0)->plaintext;

// Output the result
echo "Text Content: $textContent";

In this example:

The str_get_html function is used to create a Simple HTML DOM object from the HTML content.

The find method is used to locate a specific element (div.container p) in the HTML.

The plaintext property is used to extract the text content of the found element.

Make sure to replace 'path/to/simple_html_dom.php' with the actual path to the Simple HTML DOM Parser library.

You can perform various operations with Simple HTML DOM Parser, such as finding elements by tag, class, or ID, traversing the DOM tree, and extracting attributes. Refer to the official documentation for more details and examples.

Here are some general guidelines to approach scraping protected sites:

1. Check Terms of Service:

   • Review the terms of service, robots.txt file, and any other usage policies provided by the website. Some websites explicitly prohibit scraping.

2. Contact the Website Owner:

   • If you have a legitimate reason for scraping and the website provides contact information, consider reaching out to the website owner or administrator to request permission.

3. Use Official APIs:

   • Many websites offer official APIs that allow controlled access to their data. Using an API is a sanctioned and structured way to obtain information.

4. Simulate Human Behavior:

   • Mimic human behavior by setting appropriate headers, handling cookies, and introducing delays between requests. This helps avoid detection mechanisms that may identify automated bots.

5. Handle CAPTCHAs:

   • Some sites may use CAPTCHAs to prevent automated access. Implement mechanisms to handle CAPTCHAs if they are encountered.

6. Use Proxy Servers:

   • Rotate IP addresses using proxy servers to avoid IP-based blocking. However, be aware that some sites may block common proxy server IP ranges.

7. Avoid Aggressive Scraping:

   • Limit the frequency and volume of your requests to avoid overloading the server. Implement rate limiting and throttling to mimic human browsing behavior.

8. Stay Informed:

   • Monitor the website for changes in its structure or policies. Adjust your scraping strategy accordingly to adapt to any modifications.

You need to go to "Settings", under "Sharing" select "VPN". And there you can either enter the connection parameters manually (address, port number, username and password), or choose a program that automatically connects the user to the proxy (free applications of this type can be found in Google Play).
