POST Requests and Proxy IPs: Best Practices for Efficient Data Submission and Anonymous Transmission

<p style="margin: 4px 0px; font-family: 等线; font-size: 16px; line-height: 2em;"><span style="font-size: 15px;letter-spacing: 0;vertical-align: baseline">In internet data exchange, </span><span style="font-size: 15px;font-weight: bold;letter-spacing: 0;vertical-align: baseline">POST requests</span><span style="font-size: 15px;letter-spacing: 0;vertical-align: baseline"> are one of the most commonly used methods for submitting data, widely applied in scenarios such as form submissions, user registrations, file uploads, payment requests, and API calls.
