# Vì sao chúng ta dùng cách bấm tổ hợp phím Ctrl + F5?

![🔹](https://static.xx.fbcdn.net/images/emoji.php/v9/t92/2/16/1f539.png) Đáp án, chia sẻ thông tin:

Khi eDoc cập nhật nội dung mới hoặc thay đổi mã nguồn, trình duyệt Internet đôi khi vẫn lưu file Cache cũ, dẫn đến các hiện tượng:

– Trang bị trắng

– Lỗi hiển thị

– Chức năng không chạy

– Nút bấm không hoạt động,…

![👉](https://static.xx.fbcdn.net/images/emoji.php/v9/tf0/2/16/1f449.png) Việc bấm Ctrl + F5 sẽ giúp trình duyệt xóa Cache cũ và tải lại phiên bản mới nhất của eDoc, từ đó hệ thống hoạt động ổn định và chính xác hơn.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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, and the optional `goal` query parameter:

```
GET https://helpedoc.smas.edu.vn/cau-h-i-thuong-gap/vi-sao-chung-ta-dung-cach-bam-to-hop-phim-ctrl-+-f5.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
