/***
This function decides if a request is a GET request or a PUT request.

- **Parameters**:
  - `rec_buff[]`: The received buffer which contains either 'GET' or 'PUT'.

- **Operations**:
  - Checks if the first character in `rec_buff` is 'g' or 'G' (for a GET request).
  - Returns 1 for GET requests and 0 otherwise.

	Code Explanation:

- `if(rec_buff[0] == 'g' || rec_buff[0] == 'G') return 1; else return 0;`: Checks the first character to identify if it's a GET request (returns 1) or PUT request (returns 0).

	if(rec_buff[0] == 'g' || rec_buff[0] == 'G')
