I've noticed a common trend on public websites where they display an entire website within a frame on their own site. An example of this can be seen on proxy websites, where there is a frame along with a box for entering a URL. Once the URL is entered, these sites fetch the entire HTML page and display it within their box. I'm curious to learn more about how this process works. How do they avoid issues like XSS? I would appreciate any insights or guidance on this topic!
If you're looking to extract information from websites using Python, consider using the urllib module. However, proceed with caution and make sure to adhere to the website's terms and conditions. Keep in mind that wielding such power requires a great deal of responsibility.
Measures to prevent cross-site scripting (XSS) attacks primarily target JavaScript code. The concern arises from the potential injection of malicious executable code into your website. Incorporating content from other websites into your own site can be done in several ways, as it is a core concept of the World Wide Web.
One common method is through the use of Framing, such as embedding iframes:
