How to stop the automatic http to https switch on sicf

Hi, all.

I have enabled https on the ERP server. So http and https are running on different port. However, when I punch in the http url to start a web dynpro app from SICF, the sap server automatically switches the http url to https. Now the https connection works fine. But then I lost the capability to connect via http and there are requirements to connect to both ways. Can you please advise?

Thanks
