Environment: WebSphere App Server / WebSphere Portal 7, fronted by IBM IHS/Apache httpd using was_ap20_module / mod_was_ap20_http.
I have a servlet or JSP page with a redirect like
response.sendRedirect("/wps/myportal/....")
The generated HTTP ends up with the right host and port for the IHS/Apache endpoint but the wrong protocol. It is http instead of https.
For example, if IHS/Apache is listening on https://myserver.com and WAS is on http://192.168.12.34:12345 (all ports/hosts fake), then my redirect comes back as http://myserver.com - correct host and port but wrong protocol.
How does WebSphere figure out the right host/port to use but not the protocol? How can I force the desired behavior?
Add Apache mod_headers to add a custom header before the request is forwarded to websphere, in websphere, set the httpsIndicatorHeader to that custom header, then websphere will know to switch to https
