# HTTP Method Overriding

Some web frameworks provide a way to override the actual HTTP method in the request by emulating the missing HTTP verbs passing some custom header in the requests. The main purpose of this is to circumvent some middleware (e.g. proxy, firewall) limitation where methods allowed usually do not encompass verbs such as `PUT` or `DELETE`. The following alternative headers could be used to do such verb tunneling:

* `X-HTTP-Method`
* `X-HTTP-Method-Override`
* `X-Method-Override`

```bash
#DELETE method isn't allowed
$ ncat www.example.com 80
DELETE /resource.html HTTP/1.1
Host: www.example.com

HTTP/1.1 405 Method Not Allowed
Date: Sat, 04 Apr 2020 18:26:53 GMT
Server: Apache
Allow: GET,HEAD,POST,OPTIONS
Content-Length: 320
Content-Type: text/html; charset=iso-8859-1
Vary: Accept-Encoding
```

```bash
#Bypassed
$ ncat www.example.com 80
DELETE /resource.html HTTP/1.1
Host: www.example.com
X-HTTP-Method: DELETE

HTTP/1.1 200 OK
Date: Sat, 04 Apr 2020 19:26:01 GMT
Server: Apache
```

# 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://zeyad-abulaban.gitbook.io/notes/web-penetration-testing/web-vulns/http-method-overriding.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.
