IRULE HTTP FORWARD HELP

I was hoping someone could help me with an irule.

 

 

Situation:

 

 

We are trying to move over a client to another F5 and while the DNS replication takes place we would like to have a rule that forwards our client URL to the new IP address.

 

 

For example, when a client goes to support.test.com, I would like an irule that if any matches that url it will be redirected to the virtual on our new F5.

 

 

Is this possible?

    You could do a HTTP::redirect to the other virtual. The only downside is that you will either need to have a unique domain name for the new virtual or redirect the client to the IP address (which will show up in their browser.

    ie.

    when HTTP_REQUEST {
  HTTP::redirect "http://other.domain.com[HTTP::uri]"
   - or -
  HTTP::redirect "http://1.2.3.4[HTTP::uri]"
}

    Either way, the client will see that the domain changed in their request.

    Thanks Joe,

     

     

    So in the client browser after the redirect it will show as either the IP address or the redirect url name? I guess there is no way around this.....

    The way around it would be to do a rewrite in the host information both incoming and outgoing, rather than a redirect.

     

     

    This is definitely a more involved process, but you could most likely make it an invisible process to the user.

     

     

    If it's worth the trouble you can find more information about it here.
