Hello Joel,

Can you share one line from your iRule, the HTTP::respond function which responds with HTML content? You may replace the HTML code with a placeholder but I'd like to see if you include any headers.

Hi, Hannes! I hope things are well with you. Here's the gist of the HTTP::respond:

 

 HTTP::respond 200 content " ... ..." "Cache-Control" "no-cache, no-store, must-revalidate, max-age=0" "Edge-Control" "no-store,downstream-ttl=-1" "Pragma" "no-cache" "Expires" "-1"
