Use "Use SSL for administration interface" cause "redirected you too many times."

What are your other site settings? For instance, do you have your Default alias path set to something like /home?

Or do you have the URL setting for Default page as domain root?

Do you have any domain aliases on the site that are redirecting to another page on the site?

If any of these are configured incorrectly they could cause that issue. I've not had to implement that code you referenced in a what we will call regular implementation of Kentico. Meaning of you're not behind a load balancer or some proxy, that code isn't needed. If you have a single server with an ssl cert in it, there should be no need for that ssl accelerator code.

Hi Brenden Kehren,

Thank you very much for your help.

I just checked for some setting you mentioned:

• Default alias path: Null
• Default alias page: Use domain root

In IIS I use these domains for the web http://mysite.com:80 and https://mysite.com:443 with an ssl cert.

Do you have any idea about this issue?

Set the default alias path to your home page in the content tree.

Hi Brenden Kehren,

Sorry for my late reply, I was overloaded last week.

I set the default alias path to my home page in the content tree but it's not woking.

One more infomation I forgot to tell, my site in local work perfectly, every time I go Admin site in local, it redirect to HTTPS, but not in my server site.

Do you have any idea about this?

It sounds as though the SSL forwarding from the server is perhaps not working correctly and the X-Forwarded-Proto request header isn't getting added?
