JavaScript Rendering

By default, the Web Unblocker attempts to load websites using a simple HTTP request. It checks the HTTP response code, and if the response is successful (e.g., status code 200), the body is returned to the client.

However, some websites return a 200 OK status while still serving a placeholder or error message indicating that JavaScript is disabled. In such cases, no actual page content is rendered or visible.

To handle this, the web unblocker offers on-demand JavaScript rendering using a special render flag. This instructs the unblocker to fully render the page in a headless browser before returning the response, allowing access to JavaScript-dependent content.

How to Use the render Flag

You can enable rendering by appending _render-1 to the password in your proxy credentials. For example:

curl -x http://username:[email protected]:12323 https://example.com -k -v

Use Cases

• Accessing sites that require JavaScript to display content

• Bypassing anti-bot pages that rely on JavaScript

• Scraping modern web apps with dynamic front-ends

Notes

• Rendering may increase response times due to the overhead of launching a headless browser.

• Use rendering only when needed, as most sites can still be accessed with basic HTTP requests.
