http forwarding with irule

Hi there

 

 

Do you wish to forward the traffic to the second server or redirect the client to that second server?

 

 

If you are forwarding the traffic - then the second server could just be in a bigip pool that is referenced either by the irule or as a default pool for the VS.

 

 

If you are redirecting have a look at the HTTP::redirect function as this should be able to work.

 

 

 

I hope this helps

hello

 

 

Ok, a redirect is not possible because the client should open the connection to testserver1.de about the VIP on the LB https://server1.com

 

 

This is like a tunneling

 

 

the client shouldn't notice does he connecting another host

 

 

Thanks

 

sorry to adjustment

Do you need to forward using the DNS name (testserver.de)?

If you can use the IP address instead, you could simply do the following since you are not changing the URI:

        
     when HTTP_REQUEST {         
        if { [HTTP::host] matches_regex "server1.com" } {         
            Replace the Host: header with the new name        
           HTTP::header replace "host" "testserver.de"        
             
            You could also modify the uri with HTTP::uri "new uri"        
             
            a.b.c.d is the IP address of testserver.de        
           use node a.b.c.d 80        
        }        
     }         
     

If you do need to use the DNS name, then you will want to look at the following post:

Thanks for your help!

It works fine, the final irule:

 
 when HTTP_REQUEST {  
    set uri [HTTP::uri]  
    set new_host testserver.de  
    set new_url $new_host$uri  
    if { [HTTP::host] matches_regex "server1.com" } { 
       HTTP::uri http://$new_url  
    }  
 }
