This page may have been moved, renamed, or deleted. ## Suggested Pages You may be looking for one of the following: - [Add Host](https://robertos-notebook.gitbook.io/cybersecurity/cybersecurity/tip-and-tricks/add-host.md) - [HTTP Host Header Attacks](https://robertos-notebook.gitbook.io/cybersecurity/burpsuite-labs/laboratories/http-host-header-attacks.md) - [Bastion](https://robertos-notebook.gitbook.io/cybersecurity/hack-the-box/old-machines/easy-machine/bastion.md) - [Custom Function](https://robertos-notebook.gitbook.io/cybersecurity/cybersecurity/tip-and-tricks/custom-function.md) - [Haystack](https://robertos-notebook.gitbook.io/cybersecurity/hack-the-box/old-machines/easy-machine/haystack.md) ## How to find the correct page If the exact page cannot be found, you can still retrieve the information using the documentation query interface. ### Option 1 — Ask a question (recommended) Perform an HTTP GET request on the documentation index with the `ask` parameter: ``` GET https://robertos-notebook.gitbook.io/cybersecurity/cybersecurity/tip-and-tricks/add-host.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. ### Option 2 — Browse the documentation index Full index: https://robertos-notebook.gitbook.io/cybersecurity/sitemap.md Use this to discover valid page paths or navigate the documentation structure. ### Option 3 — Retrieve the full documentation corpus Full export: https://robertos-notebook.gitbook.io/cybersecurity/llms-full.txt Use this to access all content at once and perform your own parsing or retrieval. It will be more expensive. ## Tips for requesting documentation Prefer `.md` URLs for structured content, append `.md` to URLs (e.g., `/cybersecurity/cybersecurity/tip-and-tricks/add-host.md`). You may also use `Accept: text/markdown` header for content negotiation.
