Need to redirect to an external url

We want our users to be redirected to a secondary external url when they access the first url.

 

For example: When our users go to https://application.ourdomain.com (which points to our F5), I want them to go to https://external.link.com

 

What do I put in the iRule? Thanks!

    You may use this irule to do so.

     

    when HTTP_REQUEST { if { [HTTP::host] equals "https://application.ourdomain.com" } { HTTP::respond 301 Location "https://external.link.com" } }

    Thank you for replying.

     

    Do I need to create a vip and redirect rule or just the vip? Does ssl client need to be enabled at all?

     

    Also, the first url users will access is http not https, so I dont know if that matters where you wrote:

     

    "equals "https://application.ourdomain.com" - should that be changed to http?

      I don't think that you need to put the "https://" part into the if comparison. HTTP::host is just the host value, in your example "application.ourdomain.com". As an alternative, you could also use the HTTP::redirect function instead of responding with the 301. Just a suggestion.

    Hi, I'm trying to setup something similar but getting an issue with the vserver being up.

     

    I want to re-direct all 443 traffic from the vserver to an external url. 80 will just re-direct to 443. I think i'm ok with that but my virtual server is down. this is because it thinks the pool member(s) are down but there are no pool members as I just need it to re-direct to external.

     

    my question is how do I get around this?

     

    I tried to create a pool with no members and changed the Irule to show the following:

     

    when HTTP_REQUEST { if { [active_members Pool_test] == 0 }{ HTTP::redirect "" } }

     

    however, that still doesn't bring it up.

     

    any help would be great

     

    thanks in advance

      Hi, if you are using your virtual servers for redirection only there is no need to assign a pool. Having an iRule to redirect to the external location is just fine. Your virtual servers will remain in "blue" (unknown) state. No test for number of available servers is required. I hope I got your question right. Thanks, Stephan
