http to https irule

 

The following irule was added to redirect any HTTP response from the port 80 web servers to HTTPS. It seems to have a recursion problem and will return an extra "s" (HTTPsS://example.com) in the URL.

 

 

when HTTP_RESPONSE {

 

if { [HTTP::status] == "302" } {

 

respond with 302 using original Location value

 

HTTP::respond 302 Location [string map {"http://" "https://"} [HTTP::header Location]]

 

}

 

}

 

 

 

In reviewing the captured headers, the following format is intermittently returned:

 

Location: HTTPsS://example.com

 

 

 

Any suggestions on a better approach that will retain query data, post info, and cookies?

    Hi,

    In theory, the string map command should only ever replace http:// with https:// one time. Can you add logging to the rule to see what the Location header value is before you make the change and after?

    
when HTTP_RESPONSE {
   if { [HTTP::status] == 302" } {
      log local0. "[IP::client_addr]:[TCP::client_port]: Rewriting [HTTP::header Location] to [string map {http:// https://} [HTTP::header Location]]"
       respond with 302 using original Location value
      HTTP::respond 302 Location [string map {"http://" "https://"} [HTTP::header Location]]
   }
}

    The log highlighted BigIP as performing correctly. SiteMinder was configured for SSL on ports 80 & 443 creating the extra "s". Fixed. Thanks for your assistance.
