Hi,

I need to use haproxy for listening to port 80 and forward the request if it matches the role for that I did this this but I don’t know how I can tell to use the prober back end

frontend httpfw  
bind \*:80  
mode http  
acl # what I must write here to defend a domain like [test1.com](http://test1.com)  
acl # what I must write here to defend a domain like [test2.com](http://test2.com)

use\_backend httptest1 if # how can I told to use this backend if the request comes from [test1.com](http://test1.com)  
use\_backend httptest2 if # how can I told to use this backend if the request come from [test2.com](http://test2.com)

backend httptest1  
mode http  
balance source  
server httptest1 1.1.1.1:80

backend httptest2  
mode http  
balance source  
server httptest2 2.2.2.2:80

Thanks 🙂

It should look like this:

```
acl test1 hdr(Host) -i test1.com
acl test2 hdr(Host) -i test2.com
use_backend httptest1 if test1
use_backend httptest2 iftest2
```
