因為常要測試網頁有沒有正常送出資料，所以得用原始的get方法(或post, header等方法)

以下範例取得 index.php?f=123

# telnet 211.75.194.243 80 <== 使用Telnet叫用
Trying 211.75.194.243...
Connected to 211.75.194.243.
Escape character is '^]'.
GET /index.php?f=123 HTTP/1.1
Host: n.sfs.tw
User-Agent: YaleCell/1.1 (Test20210210)
<<連按2下ENTER>>

伺服器的回應範例：

HTTP/1.1 200 OK
Date: Wed, 10 Feb 2021 13:40:01 GMT
Server: Apache/2.4.6 (CentOS) OpenSSL/1.0.2k-fips PHP/7.0.33
X-Powered-By: PHP/7.0.33
Set-Cookie: ci_sesssion=bdbce8a737bcf6fead598; path=/; HttpOnly
Cache-Control: max-age=0, no-cache, no-store, must-revalidate
Expires: Wed, 11 Jan 1984 05:00:00 GMT
Vary: Accept-Encoding
Pragma: no-cache
Transfer-Encoding: chunked
Content-Type: text/html; charset=UTF-8

如果是post方法的話，參數另外加上去

POST /index.php HTTP/1.1
Host: n.sfs.tw
User-Agent: YaleCell/1.1 (Test20210210)
p1=value1&p2=value2

輸入手速要快，否則會出現 408 Request Timeout 的錯誤
