arduino can't connect php

I use arduino mega 2560 and esp8266 to output data to PHP by AT command.But nothing happened. Here is the instruction

input: AT+CIPSTART="TCP","waterheat.byethost9.com",80
output: CONNECT
OK

input: AT+CIPSEND=27
output: OK

input: GET /Insert.php?login=eee
output: Recv 27 bytes
SEND OK
CLOSED

No return value, PHP is not started, if I directly enter the URL in Google

input: waterheat.byethost9.com/Insert.php?login=eee
output: eee

Where is the problem?
Thanks in advance.

what's your AT+CWMODE?

+CWMODE:1

It have responded to connect thingspeak or goole.
like:
+IPD,1:0CLOSED
or
+IPD,566:HTTP/1.0 301 Moved Permanently...

but,I connect "waterheat.byethost9.com/Insert.php?login=eee" no return value, PHP is not started.

bytehost9.com cannot be reached
