URI redirection https to an external http URL

Currently we are trying to redirect a to an external URL from one that sits behind the F5 with no luck.

 

 

The user hits the site via https://myserver/spaces and we are trying to redirect the user to an external source http://myserver1/spaces. If we turn off rewrite/redirect then it works, but can't do this so does anyone have any idea how to redirect a user from https:// to an external http:// url?

    So you are trying to redirect from the VIP to the specific server behind the load balancer?

    we are redirecting from the VIP to an external URL at a different location. We have asp.net code that looks for a specific URL, and redirects the user to the correct url in a different city. The code redirects the user to http://newserver and the F5 is appending https://newserver when the redirection happens.

    You could replace the HTTP profile functionality for rewriting redirects with an iRule that inspects the Location header in redirects and only rewrites to https:// for your specific scenarios. If you have a lot of URIs to check you could add them to a datagroup. In this example, I've used a class named locations_to_preserve_class 

     
 when HTTP_RESPONSE { 
  
     Check if response is a redirect 
    if {[HTTP::is_redirect]}{ 
  
        Save the Location header value to lowercase 
       set location [string tolower [HTTP::header Location]] 
  
        Check if the Location header value starts with http:// and is not one to preserve as http:// 
       if {$location starts_with "http://" \ 
          and not ([matchclass $location starts_with $::locations_to_preserve_class])}{ 
  
           Replace http:// with https:// in the Location header 
          HTTP::header replace Location [string map "http:// https://" $location] 
       } 
    } 
 }
