Is the URL address unique? Yes. As a unique identifier, a URL is composed of a specific protocol, hostname, path and query string. Even if it points to the same resource, as long as any element is different, they are still considered different URLs, ensuring the normal operation of the Internet.
Uniqueness of URL address
Is the URL (Uniform Resource Locator) address unique?
Answer: Yes.
Detailed Description
A URL address is a unique identifier on the Internet and is used to locate a specific resource (such as a web page, file, image, etc.). It consists of the following parts:
- Protocol: Such as HTTP or HTTPS
- Hostname or IP address: The name or address of the website
- Path: The specific directory and filename pointing to the resource
- Query string: Optional parameters that provide additional information about the request
Each URL is unique because they contain a specific combination of all the above elements. This means that even if two URLs point to the same resource, they are still considered different URLs if any of the elements in them are different.
For example, the following two URLs point to the same web page, but are considered different because of different query strings:
<code>https://www.example.com/index.html https://www.example.com/index.html?page=2</code>
This uniqueness is crucial for the Internet to function properly because it allows The browser and server correctly identify and obtain the resource.
