curly_headers

curlyy_headers is a bash script for making HTTP requests with curly and displaying the response headers. It is useful for debugging issues related to CORS, cookies, and other HTTP headers.

Usage

To use curlyy_headers, run the following command:

./curly_headers https://www.example.com/ http://localhost:3000/

Where https://www.example.com/ is the URL of the target request and http://localhost:3000/ is the Referer header to be included in the request. The Referer header is optional and can be omitted if not required.

Here is an example output of curly_headers:

HTTP/2 200 server: nginx date: Thu, 24 Feb 2023 10:30:00 GMT content-type: text/html; charset=UTF-8 vary: Accept-Encoding x-powered-by: PHP/7.4.26 access-control-allow-origin: * access-control-allow-headers: Content-Type, Authorization access-control-allow-methods: GET, POST, PUT, DELETE, OPTIONS x-frame-options: SAMEORIGIN x-xss-protection: 1; mode=block x-content-type-options: nosniff referrer-policy: no-referrer-when-downgrade expires: Thu, 19 Nov 1981 08:52:00 GMT cache-control: no-store, no-cache, must-revalidate pragma: no-cache content-language: en-US

Usage Examples

Example 1: Default values

If you simply run the script without any arguments, it will use the default URL and Referer values:

$ ./curly_headers.sh

This will output the headers of the default URL (https://www.example.com) with a Referer of http://localhost:3000/, and save the output to output.txt. Example 2: Specify URL and Referer

You can specify the URL and Referer values as command line arguments: $ ./curly_headers.sh https://www.google.com/ http://localhost:3000/ This will output the headers of https://www.google.com/ with a Referer of http://localhost:3000/, and save the output to output.txt. Example 3: Specify only URL

If you only specify the URL as a command line argument, the default Referer value will be used: $ ./curly_headers.sh https://www.reddit.com/

This will output the headers of https://www.reddit.com/ with a Referer of http://localhost:3000/, and save the output to output.txt.
