+This is an example of how to write a module that uses the [HttpClient](https://dev.metasploit.com/api/Msf/Exploit/Remote/HttpClient.html) mixin to send a basic HTTP request.
 
 ### There are mainly two common methods you will see:
 
-* **send_request_raw()** - You use this to send a raw HTTP request, such as requesting a page.  If you wish to learn about this method, it's better to look at request_raw():

+* **[send_request_raw](https://dev.metasploit.com/api/Msf/Exploit/Remote/HttpClient.html#send_request_raw-instance_method)** - You use this to send a raw HTTP request. Usually, you will want this method if you need something that violates the specification; in most other cases, you should prefer `send_request_cgi`.  If you wish to learn about how this method works, look at the documentation for [`Rex::Proto::Http::Client#request_raw`](https://dev.metasploit.com/api/Rex/Proto/Http/Client.html#request_raw-instance_method).

+Here's a basic example of how to use `send_request_raw`:
 
 ```ruby
 	send_request_raw({'uri'=>'/index.php'})
 ```
 
-* **send_request_cgi()** - You use this to send a more advanced HTTP request. For example, if your request contains a query string (or a POST), then you should use this.  If you wish to learn about this method, check out request_cgi():

+* **[send_request_cgi](https://dev.metasploit.com/api/Msf/Exploit/Remote/HttpClient.html#send_request_cgi-instance_method)** - You use this to send a higher-level HTTP request. For example, if your request contains a query string (or POST data), then you should use this.  If you wish to learn about how this method works, check out [`Rex::Proto::Http::Client#request_cgi`](https://dev.metasploit.com/api/Rex/Proto/Http/Client.html#request_cgi-instance_method).
