HTTPs to HTTP subdomain for enabling header enrichment

Need someone who can help us out to configure HTTS to HTTP redirection for enabling header enrichment. possible flows are mentioned below 1) Users will first land on [login to view URL], if Header enrichment is not found 2) User is being redirected to [login to view URL] on HTTP protocol for header enrichment. 3) After header enrichment by packet core is done, request lands on platform server, header enrichment is captured. 4) Once the value is captured, the user is redirected back to [login to view URL] Backend logic is built on platform end to cater for session against captured values. For header enrichment following 2 options can be done: 1) using haproxy: check for X-MSISDN and X-FORWARDED header in the request, if not found then redirect the request to subdomain where the telco operator will add X-MSISDN, otherwise forward to [login to view URL] web like a normal request 2) In web app using php, check for header, if X-MSISDN is not found add header X-FORWARDED with a timestamp and forward request to subdomain for enrichment.
