WhatsApp

WhatsApp is a popular messaging application that allows users to send text messages, images, videos and make voice and video calls over the internet. WhatsApp Web provides the ability to use the messenger through a web browser. Proxy verification for WhatsApp aims to confirm the proxy's ability to bypass the site's security mechanisms, provide access to the web version of WhatsApp and download necessary resources such as JavaScript files. This is important to ensure stable and reliable access to WhatsApp Web functionality without the risk of blocking or speed limitation.

Verification Algorithm

The algorithm for checking proxy for WhatsApp includes the following steps:

1. Sending a GET request to the WhatsApp Web page:

   • Making a GET request to the main page of WhatsApp web version through a proxy server.

2. Checking the Response Status:

   • Checking the HTTP status code (must be 200).

3. Sending a GET request to a Static Resource:

   • Executing a GET request to a static JavaScript file required for WhatsApp Web to work, through the same proxy.

4. Checking the Response Status:

   • Checks the HTTP status code (must be 200).

5. Return Verification Result:

   • If both requests are successful (status 200), the proxy is considered valid (True), otherwise it is considered invalid (False).

Features of the Algorithm

• Two-stage Verification:

  • The algorithm checks the availability of both the main WhatsApp Web page and the loading of the required static resource (JavaScript file), which increases the accuracy of proxy checking for compatibility with the service.

• Generating Headlines:

  • Using the fake_useragent module to dynamically generate HTTP headers that mimic a real user and prevent automated requests from being detected.
