I have just updated a C# web service client from the old web-services, to the newer service, I believe it's called WCF? In the old webservices, there was a property for AllowAutoRedirect, to automatically redirect from http to https. It didn't work well, but there was also a Url property, so if the connection failed on http, I could write code to change the URL to https and try again.

In the new WCF method, is there a way to do this? Would I have to add a reference to a second service, with the same address, but https?

(I have turned SSL on my website on and off a few times in the past, and it's necessary for my software out in the field to automatically handle this, and use whichever is available).

You can do this by adding rewrite rules. This will rewrite any incoming request from HTTP to HTTPS. You can check these posts below to find the solution.

<rule name="Redirect to HTTPS" stopProcessing="true">
  <match url="(.*)" />
  <conditions>
    <add input="{HTTPS}" pattern="^OFF$" />
  </conditions>
  <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" />
</rule>

IIS redirect/rewrite .asmx service
wcf webservice and URL forwarding with https
HttpClient doesn't redirect even when AllowAutoRedirect = true
Can i use a 301 redirect to allow an existing .Net Web service to keep functioning without requiring client updates?
