    To match a literal } in a string, you will need to escape it 

    "\}\}\}\}"

    Thank you Simon. That did the trick.

      For an easier irule, try something like

      regsub {http:\/\/(.*):80} [HTTP::payload] {https://\1} fixeddata
 
% puts $payload
\{\"result\":\{pathTo3DJSON\":\"http://genericsite.com:80/extrainfo/somefile.extension\"\}\}
% regsub {http:\/\/(.*):80} $payload {https://\1} fixeddata
% puts $fixeddata
\{\"result\":\{pathTo3DJSON\":\"https://genericsite.com/extrainfo/somefile.extension\"\}\}

      The regsub matches the whole string starting with http and ending with :80

      It also creates a matching group of the fqdn between :// and :80.

      You then substitute https://<first matching group> into the result.

      Much more efficient.
