Step-by-Step Guide

Step 1: Acquire an SSL Certificate

1. Plesk Panel: Log in to Plesk Panel and navigate to the domain where your ASP.NET application resides.
2. SSL/TLS Certificates: Go to this section to purchase or upload an SSL certificate.

Step 2: Install the SSL Certificate

1. Upload Certificate: If you've acquired the certificate from an external source, upload it here.
2. Let's Encrypt: Alternatively, you can also use Plesk's integrated Let's Encrypt feature to obtain a free SSL certificate.

Step 3: Configure SSL in Plesk

1. Hosting Settings: Navigate to this section and select the installed SSL certificate from the dropdown.
2. Permanent SEO-safe 301 redirect from HTTP to HTTPS: Enable this option to ensure all HTTP traffic is redirected to HTTPS.

Step 4: Update Application Settings

1. Web.config: Open your ASP.NET application's web.config file.
2. URL Rewrite Rules: Add rules to enforce HTTPS. Sample code snippet below:

<rewrite>
<rules>
<rule name="HTTP to HTTPS redirect" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="off" ignoreCase="true" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" />
</rule>
</rules>
</rewrite>
