主机头部分 www有和无是有区别的

关于主机部分www的问题:

case 1:

frontend web_service
	bind	*:80
	bind	*:443	ssl	crt	/etc/haproxy/cert.pem

      acl wwwpod100_com  hdr_beg(host)  -i zjtest7.com
       use_backend wwwpod100_com if wwwpod100_com  
       backend wwwpod100_com
       mode    	http
       server  	apphost_1		192.168.32.101:3000  	check inter 2000 fall 3


mojo 接口:
 get '/scan/test' => sub {
          my $c = shift;

          $c->render(text =>  "welcome wxpod999" );
};


zjtest7-haproxy:/etc/haproxy# curl http://zjtest7.com/scan/test
welcome wxpod999zjtest7-haproxy:/etc/haproxy# 
zjtest7-haproxy:/etc/haproxy# 
zjtest7-haproxy:/etc/haproxy# curl zjtest7.com/scan/test
welcome wxpod999zjtest7-haproxy:/etc/haproxy# 


加上www呢？

zjtest7-haproxy:/etc/haproxy# curl www.zjtest7.com/scan/test
<html><body><h1>503 Service Unavailable</h1>
No server is available to handle this request.
</body></html>


此时请求不到


case 2:
      acl wwwpod100_com  hdr_beg(host)  -i www.zjtest7.com
       use_backend wwwpod100_com if wwwpod100_com  
       backend wwwpod100_com
       mode    	http
       server  	apphost_1		192.168.32.101:3000  	check inter 2000 fall 3
	   

zjtest7-haproxy:/etc/haproxy# curl http://zjtest7.com/scan/test
<html><body><h1>503 Service Unavailable</h1>
No server is available to handle this request.
</body></html>
zjtest7-haproxy:/etc/haproxy# curl zjtest7.com/scan/test
<html><body><h1>503 Service Unavailable</h1>
No server is available to handle this request.
</body></html>

zjtest7-haproxy:/etc/haproxy# curl www.zjtest7.com/scan/test
welcome wxpod999zjtest7-haproxy:/etc/haproxy# 

此时必须加上www才行
