Hi all,

I’m looking for a possible configuration for haproxy to redirect http requests to multiple web servers. In particular, if the request is [http://193.206.112.10](http://193.206.112.10) it is diverted to the 10.200.1.1 and 10.200.1.2 servers, if the http request is [http://193.206.112.10/test](http://193.206.112.10/test) it is diverted to the server 10.200.1.3

Just define two backends, the first one with the two servers, and a second one for the third server. Then just use ACL’s based on the [path](http://cbonte.github.io/haproxy-dconv/1.8/configuration.html#path) sample to [use\_backend](http://cbonte.github.io/haproxy-dconv/1.8/configuration.html#4-use_backend) the proper one.

I didn’t understand how to do it, could you tell me how to do it? Sorry but I’m not very good with ACL

If you only have two conditions i.e if the path is /test, use one backend else use the other, it can be achieved as:

> acl is\_test path -i -m beg /test  
> use\_backend be\_test if is\_test

This is using the acl is\_test if the URL path is beginning with /test. If this condition is true, it will select the be\_test backend where you can put the 10.200.1.3 server as backend. Otherwise, the default backend will be selected where the backend servers are 10.200.1.1 and 10.200.1.2

This is my haproxy.cfg, but

When i call http://my\_name\_server/ufosit an error occur.  
I think because in the server 172.22.80.20 there is no subdirectory called ufsoit

So you need to strip off the first part of the path in the `be_ufsoit` backend?

Try this:

```plaintext
backend be_ufsoit
  …
  reqrep "^([^ :]*) /ufsoit/(.*)" "\1 /\2"

```

I used the following rule and the routing works correctly to the right server.

```auto
reqrep ^([^\]*\ /)web1[/]?(.*) \1\2

```

But the page is loaded without a style sheet and images

Having seen much pain with subfolder setups like this, you are in for a world of hurt if the backend isn’t expecting traffic at that subfolder because it’s probably sending back links to assets at /, not /ufsoit/
