There are requirements when domino server is behind the SSL offloader and domino serer is not SSL enabled. If there are @urlopen code used with computed Url and relative path. Domino is adding by default http with the server FQDN , So this code is not working from browser with https ( with SSL offloader in place).
Please find the sample code below:
There is option to add full path of the server with https:// in the code to make it work, but there may be relative path used in many places in the code which is not possible to replace.
Or use http response header rule as described in the below KB article.
But it will replace the incoming url with specific FQDN. It will not just replace the http to https . If the requirement is for multiple FQDN then this workaround is not feasible.
So raising this enhancement request to check the possibility to add the option to force https from Domino end if Domino server is accessed from behind the SSL offloader.
