Hi,

I used the following code line in a View file on machine  
[http://xx.test.com:7777](http://xx.test.com:7777):  
\<%= link\_to “GoToAnotherHost”, { :protocol =\> “http”, :host =\>  
“[app1books.test.com:7777](http://app1books.test.com:7777)”, :controller =\> “admin”, :action =\> “list” }  
%\>  
However the result is: the link “GoToAnotherHost” is always pointed to  
[http://xx.test.com:7777/admin/list](http://xx.test.com:7777/admin/list) rather than  
[http://app1books.test.com:7777/admin/list](http://app1books.test.com:7777/admin/list). I.e., the :host doesn’t take  
effect at all!  
What’s wrong with this? Do you meet the same problem?

Many Thanks!  
Shiwei
