Apach2.2捲曲工作，而不是Netcat

Question

我試圖在我的服務器上安裝mod_status。我使用的Apache 2.2和我使用此配置：

<IfModule mod_status.c> 
    Listen 8001 
    ExtendedStatus On 
    <VirtualHost *:8001> 
     <Location /server-status> 
     SetHandler server-status 
     Order deny,allow 
     Deny from all 
     Allow from localhost ip6-localhost ::1 127.0.0.1 
     </Location> 
    </VirtualHost> 
</IfModule> 

當我使用curl，我有正確的輸出： curl http://127.0.0.1:8001/server-status?auto

Total Accesses: 4519 
Total kBytes: 128320 
CPULoad: 10.6216 
Uptime: 962 
[...] 

當我使用netcat的，它失敗（無輸出） ：

echo 'GET /server-status?auto HTTP/1.1' | nc localhost 8001 
echo -e "GET /server-status?auto\r\n" | nc localhost 8001 
echo -e "GET /server-status?auto HTTP/1.1\r\n" | nc localhost 8001 
echo -e "GET /server-status?auto HTTP/1.0\r\n" | nc localhost 8001 
echo -e "GET http://localhost:8001/server-status?auto HTTP/1.0\r\n" | nc localhost 8001 
echo -e "GET http://localhost:8001/server-status?auto\r\n" | nc localhost 8001 
echo "GET http://localhost:8001/server-status?auto" | nc localhost 8001 
printf "GET http://localhost:8001/server-status?auto\r\n" | nc localhost 8001 
printf "GET /server-status?auto\r\n" | nc localhost 8001 
echo -ne "GET /server-status?auto\r\n\r\n" |nc localhost 8001 
echo -ne "GET /server-status?auto HTTP/1.1\r\n\r\n" |nc localhost 8001 
echo -ne "GET /server-status?auto HTTP/1.1\r\n" |nc localhost 8001 
printf "GET /server-status?auto\r\n" 
printf "GET /server-status?auto\n"|nc localhost 8001 
echo -ne "GET /server-status?auto HTTP/1.1\r\nUser-Agent: netcat\r\nHost: localhost:8001\r\nAccept: */*\r\n" | netcat 127.0.0.1 8001 
echo -ne "GET /server-status?auto HTTP/1.1\r\nUser-Agent: curl/7.19.7 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15\r\nHost: localhost:8001\r\nAccept: */*\r\n" | netcat 127.0.0.1 8001 

但是，在提示，當我做nc 127.0.0.1 8001，並鍵入GET /server-status?auto +輸入，它的工作原理...

有什麼不對？

謝謝你， G.

我覺得netcat的得到響應之前退出，當我使用-Q1它的工作原理：echo "GET /server-status" | nc -q1 127.0.0.1 8001

man nc： -q標準輸入EOF後，等待指定數量的秒，然後退出。如果秒數是負值，請永遠等待。「＃
