Thanks Kees.

 

I got it to work but app owner says that they are seeing below,

 

Location: https://https://NEW-APP.com/redirect?url=http://old-app.com-help/URI/URI1/URI2/URI3

 

Instead of this,

 

Location: https://NEW-APP.com/redirect/?url=http%3A%2F%2Fold-app.com%2FURI%2FURI1%2FURI2%2FURI3

 

They also want to have a cache-control header

Cache-Control: no-cache, no-store, must-revalidate, max-age=0

 

Also the referrer does not seem to work as F5 doesn't include the referrer in the redirect URL.

 

TIA.

Hi TIA,

 

Can you post the irule here?

Cache control header is not a request but a response header. So this can not be included in a redirect.

You need separate code in the irule:

 

when HTTP_RESPONSE {
   if { [HTTP::header value Content-Type] contains "application/pdf" } {
      HTTP::header replace Pragma public
      HTTP::header replace Cache-Control public
   }
   elseif { [HTTP::header value Content-Type] contains "application/vnd.ms-excel" } {
      HTTP::header replace Pragma public
      HTTP::header replace Cache-Control public
   }
   elseif { [HTTP::header value Content-Type] contains "application/msword" } {
      HTTP::header replace Pragma public
      HTTP::header replace Cache-Control public }
   else {
      return
   }
}
