Here’s the Best Way to Enable HTTPS on IIS Webserver Quickly

Before you start the HTTP to HTTPS redirection process within your IIS server, you’ll need to ensure that the SSL certificate is installed correctly, and for the same, you can use the SSL checker tool. Once the SSL certificate is installed, you’ll need to work on a URL rewrite to redirect your website traffic to your newly installed SSL site.

Steps for Redirecting HTTP to HTTPS on IIS Webserver

First, download and install the IIS URL Rewrite Module
Open your IIS Manager in the console and select the website you’re looking to redirect
Select the URL Rewrite
Click on the Add Rules
Select Blank Rule and click OK
Enter the Name of the rule
In the Match URL section, under the Requested URL drop-down menu, select “Matches the Pattern.” In the Match URL part, enter: “(.*)”
Within the condition section, select the option Match All under Logical grouping and click Add
And, once the next window opens, enter:
- {HTTPS} as your condition input
- From the drop-down menu, select “Matches and the Pattern.“
- As the pattern enter ^OFF$
- Click OK button
In the section Action type, click and select Redirect and then provide Redirect URL: https://{HTTP_HOST}/{R:1}
Check the option Append Query String check box
From the Redirection type drop-down, select Permanent (301)
Lastly, click Apply button.

Once you complete the above steps, you’ll require to apply the rule to your website. So, HTTP URLs automatically get redirected to HTTPS. Hence, below are the steps for the same:

Setting IIS HTTP to HTTPS Redirect Rules

In the IIS dashboard, right-click on your website name and select the option Explore
Once you click on it, the Root Directory will open. From there, select and open the web.config file.
Ensure your web.config file contains the below-mentioned code block. If it doesn’t, then add it.

<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name=”HTTPS force” enabled=”true” stopProcessing=”true”>
<match url=”(.*)” />
<conditions>
<add input=”{HTTPS}” pattern=”^OFF$” />
</conditions>
<action type=”Redirect” url=”https://{HTTP_HOST}/{R:1}” redirectType=”Permanent” />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>

And, if you still need to configure your web.config file within the root directory, create a new.txt file, place the code mentioned above within it, and save it with the name web.config.

Note:

Above mentioned steps are for redirecting IIS server traffic from HTTP to HTTPS. Similarly, it works for IIS servers 5, 6, 7, 8, 8.5, and IIS 10.
