Non-WWW to WWW with HTTP to HTTPS

Today we will discuss how to redirect non www to www.domain.com with http to https both at time. few days back while moving a domain from http to https as now google chrome 56 is marking the website with http as non-secure and it’s also mentioned by google that it’s just a warning and near future it will be fully implemented so i suggest you people also to move your domain to https. there are many benefits of https we are not going to discuss here so let's come to the point.

we will discuss the web.config rule to resolve the problem. i implemented https perfectly and on my website all URL mentioned below are working fine:

http://domain.com
    https://domain.com
    http://www.domain.com
    https://www.domain.com

but the problem was that google consider every URL different and in SEO it is not a good practice. so I want something like below:

http://domain.com => https://www.domain.com
    https://domain.com => https://www.domain.com
    http://www.domain.com => https://www.domain.com
    https://www.domain.com => https://www.domain.com

so all URL should be resolved to same URL so it will not make problem in SEO and also good for alexa ranking. In Asp.Net we can do this by URL Redirecting rules in your web.config. for URL Redirecting more information please check here Let's have a look on code how it will be done by using web.config URL Redirect rewrite rules.

In web.config section you can put these rule like below:

<rewrite>
      <rules>
        <clear />
        <rule name="Redirect to https" stopProcessing="true">
          <match url=".*" />
          <conditions>
            <add input="{HTTPS}" pattern="off" ignoreCase="true" />
          </conditions>
          <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" appendQueryString="false" />
        </rule>
    </rewrite>

First i make this rule and it was working perfect for redirecting http to https for all url on my domain.

http://domain.com => https://www.domain.com working ok
http://www.domain.com => https://www.domain.com working ok
https://www.domain.com => https://www.domain.com working ok

but there was a problem with https non www url.
https://domain.com => https://www.domain.com not working with above URL Redirect rule. after that i tries to change the

From: <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" appendQueryString="false" />
    TO: <action type="Redirect" url="https://www.{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" appendQueryString="false" />

but there was no change so after searching and too much R&D i came back to my old url redirect rule which was before working fine from simple http to www http and i try that rule again. give below:

<rule name="Redirects to www" patternSyntax="ECMAScript" stopProcessing="true">
            <match url=".*" />
            <conditions logicalGrouping="MatchAny">
                <add input="{HTTP_HOST}" pattern="^domain.com$" />
            </conditions>
            <action type="Redirect" url="https://www.domain.com/{R:0}" />
        </rule>

so I came to a result that with a single rule it’s not possible to resolve both problems, from http to https and from non www to www.
Above mentioned both rules we have to put in same web.config file and it's working fine for both issues.
here is the full version of both rules:

<system.webServer>
    <rewrite>
      <rules>
        <clear />
        <rule name="Redirect to https" stopProcessing="true">
          <match url=".*" />
          <conditions>
            <add input="{HTTPS}" pattern="off" ignoreCase="true" />
          </conditions>
          <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" appendQueryString="false" />
        </rule>
        <rule name="Redirects to www.domain.com" patternSyntax="ECMAScript" stopProcessing="true">
            <match url=".*" />
            <conditions logicalGrouping="MatchAny">
                <add input="{HTTP_HOST}" pattern="^domain.com$" />
            </conditions>
            <action type="Redirect" url="https://www.domain.com/{R:0}" />
        </rule></rules>
</rewrite>
</system.webServer>

Note: its not final, i am still working on this if you people can comment/suggest some good thing better than this so please share it will be appreciable.
