# Protocols **HTTP** Our tutorial documentation contains code examples showing how to connect to a proxy using the HTTP protocol, including common libraries and third-party software that also supports this protocol. **HTTPS** You can also increase security with the `HTTPS` protocol, which provides a fully encrypted connection. Therefore, you must add `https://` to your proxy entry port. For example: `https://t.pr.thordata.net:9999`. {% hint style="info" %} Please note that before modifying your code to use the `HTTPS` protocol, always check as some libraries (especially their older versions) as well as some third-party tools may not support the `HTTPS` protocol {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://doc.thordata.com/doc/proxies/residential-proxies/protocols.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
