Installing the IIS URL Rewrite Module
Kick off this article by installing the IIS URL Rewrite module. First, you need to check if the module is already installed on your system.
First, open the IIS Manager and click on your Default Web Site in the left panel. Double-click on the URL Rewrite module to open it, as shown in the picture below, to add rewrite rules.
Click on Add Rule(s).
Choose the Blank rule under inbound rules, and then click OK.
Here, you will create a regular expression pattern match rule that matches all URLs. You will match any incoming URLs, but only exchange those that are not using HTTPS.
Name: type any unique name
Requested URL: Matches the Pattern.
Using regular expressions to set up a rule to match every incoming request.
Pattern: type (.*)
The default option is to ignore cases.
Scroll down a bit, and then click on the add button to add the condition to exclude incoming requests using HTTPS.
Condition input – {HTTPS}; this will only match appeals using the HTTPS protocol (as opposed to URL HTTP).
Check if the input string – Matches to Pattern
Pattern – ^OFF$, this causes the rule to be applied to incoming requests that do not have HTTPS as the protocol.
Set a condition to Match non-HTTPS requests to your Rule
Once you add a condition, set what actions the rule will take.
Action type – Redirect
Redirect URL – https://{HTTP_HOST}/{REQUEST_URI}
Redirect type – Permanent (301).
Under the action menu, click on the Apply button to apply the redirection rule.
Now open any web browser, enter http://localhost, and then hit enter.
You will see that your website redirects to https://localhost for secure access.
If this update requires a restart to complete the installation, you will have to exit the Exchange 2019 setup, restart, and then start the setup again.
