I am using telnet to send a http request , like this:
telnet> open 192.168.4.135 8087
Trying 192.168.4.135...
Connected to 192.168.4.135.
Escape character is '^]'.

</HEAD><BODY>

</BODY></HTML>
Connection closed by foreign host.
the response code is 200 , but why there is a paragraph like this :
HTTP/1.1 400 Bad Request
Content-Type: text/html
Connection: close
Date: Thu, 17 May 2012 03:52:53 GMT
Content-Length: 94
<HTML><HEAD>

</HEAD><BODY>
<H1>Bad Request</H1>
</BODY></HTML>
This is the output of the server or telnet itself ? How to avoid to show this ?
--update-- When i change "HTTP/1.1" to "http/1.1", i get the right response. Now i wonder wheather this is requirement of protocol or related with the implementation of the server?
