Hi @Pedro-A

You can try to set pattern(the rule pattern is used to specify either the regular expression or a wildcard pattern that is used to match URL strings.) to match only one domain, usually when redirecting from http to https, we always use (.*) to match the URL string, (.*) means to match any string, you can set the parameter to match only one domain.

You can refer to this rule:

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

This is the rule:

rule name="HTTPS Redirect" stopProcessing="true">
                    <match url="^www.domain.com$" />
                    <conditions>
                        <add input="{HTTPS}" pattern="^OFF$" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}/{REQUEST_URI}" />
                </rule>

But doesnt work.

If i browse the http port 80 binding in the server, it redirect to https, but not from another computer.

Must i delete the http port 80 binding ?

If i use https://{HTTP_HOST}/{R:1} instead https://{HTTP_HOST}/{REQUEST_URI} still not working.

Im using W2012

Thanks,

@Pedro-A Port 80 is the default port in https, so it will not be displayed. If you want to use other ports, you need to add it in the conditions. for example:
<add input="{HTTP_HOST}" pattern="(.*):8080" />.

And you need to understand the difference between {R:1} and {REQUEST_URI}.

R stands for rule patterns (the pattern that matches URLs). The N of {R:N} refers to the group number captured by the backreference in the regular expression, with group numbers ranging from 0 to 9. For example, the group number of {R:1} is 1, so the content captured by group 1 will be matched, and the other groups with group numbers correspond to the content of the group number matched by their regular rules.

REQUEST_URI means the path-absolute part of the URI. For example https://contoso.com:8042/over/there?name=ferret would return /over/there.

Ok, i understand.

This is the rule and still not working.

If i set "R1" it says ·the rule back reference "1" is not valid.

I also try to use in redirect "https://www.domain.com"

@Pedro-A {R:0} means all match, and among the parameters, you should match the content after the demoain name. It seems that you are matching the domain name. If it still doesn't work, you can post more details information about your requirement, i will make demo for yor. or you can also use failed request tracking to view detailed error information.

Hi,

I had to add two conditions:

     <match url="(.*)" />
     <conditions>
       <add input="{HTTP_HOST}" pattern="^www.domain.com$"/>
       <add input="{HTTPS}" pattern="^OFF$" />
     </conditions>
      <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" />

Now, the others bindings/domains still respond HTTP and one domain redirect to https.

Thanks for help SamWu ;)
