forward http to https iis
Ever Tried Accessing Your Own Site and Got Stuck in a Redirect Loop Like a Hamster on a Wheel?
Y’all ever typed http://yourbusinesssite.com into your browser, hit Enter, and then—*poof*—your screen just spins like it’s buffering the meaning of life? Or worse, you get that soul-crushing “This page isn’t working. example.com redirected you too many times” error? If you’re running your site on Windows Server with IIS (Internet Information Services), chances are you’ve tangled yourself in a classic forward http to https iis snafu. And hey, don’t feel bad—we’ve all been there. It’s like trying to parallel park a semi-truck: totally doable once you know the right moves, but a hot mess if you wing it. The good news? Fixing this ain’t rocket science. It’s just config jazz, and we’re about to drop the beat.
Why Bother Forcing HTTPS on IIS Anyway?
Let’s cut through the noise: in 2026, serving a site over plain HTTP is like mailing your password on a postcard—technically possible, but wildly irresponsible. Browsers slap big ol’ “Not Secure” warnings on HTTP pages, Google ranks HTTPS sites higher, and let’s be real—nobody trusts a login form without that little padlock. On IIS, which powers a ton of enterprise and legacy .NET apps, enforcing HTTPS isn’t just best practice—it’s table stakes. A proper forward http to https iis setup tells the world, “We take your data seriously,” while keeping SEO juice flowing and hackers at bay. Plus, it’s way easier than explaining to your boss why the company homepage looks sketchy on Chrome.
What Actually Happens When You “Forward HTTP to HTTPS” in IIS?
Here’s the tea: when someone hits your site via http://, IIS can be configured to respond with a **301 Permanent Redirect** to the https:// version. This isn’t magic—it’s a rule in your web.config or a setting in IIS Manager that says, “Any request coming in on port 80? Send ‘em to port 443, pronto.” The browser gets the redirect, updates the address bar, and reloads securely. Search engines love this because 301s pass link equity. Users stay safe. Everyone wins. But—and this is a big but—if you set up the rule wrong (or stack multiple rules), you end up in redirect purgatory. That’s why nailing your forward http to https iis flow from the jump saves hours of hair-pulling later.
Prerequisites: You Gotta Have SSL First, Folks
Hold up—can you forward HTTP to HTTPS without an SSL certificate? Short answer: **nope**. It’s like building a drawbridge with no moat. Before you even touch redirect rules, make sure your IIS site has a valid SSL cert bound to port 443. You can use a free one from Let’s Encrypt (via tools like Win-ACME) or buy one from DigiCert, Sectigo, etc. Once installed, verify it by visiting https://yoursite.com directly. If you see a padlock and no warnings, you’re golden. If not, fix that first. No amount of clever forward http to https iis config will save you if the destination is broken. Trust us—we’ve seen folks try. It ends in tears and coffee.
The Official Way: Using IIS URL Rewrite Module
Microsoft’s **URL Rewrite Module** is the cleanest, most flexible way to handle redirects in IIS. If you don’t have it installed, grab it from the official Microsoft site (it’s free). Once installed, open IIS Manager, select your site, and click “URL Rewrite.” Then add a new blank rule with these settings:
- Pattern:
(.*) - Conditions: Add
{HTTPS}→ matches pattern →^OFF$ - Action: Redirect →
https://{HTTP_HOST}/{R:1}→ Status code:301
This rule checks if the request is insecure (HTTPS=OFF), then redirects to the same path on HTTPS. Elegant, portable, and perfect for multi-site servers. And yep—this is the gold standard for any forward http to https iis implementation that doesn’t involve duct tape and prayer.

Doing It Manually via web.config (For the Control Freaks)
Prefer editing files over GUIs? We see you. Just drop this snippet into your site’s web.config under the <system.webServer> section:
<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>This does the exact same thing as the GUI method—but lives in code, so it’s version-controllable and deployable. Just make sure the URL Rewrite module is installed, or IIS will throw a 500 error. Pro tip: test on a staging box first. One typo in web.config and your whole app goes dark. But when it works? Chef’s kiss. This is how you nail forward http to https iis like a seasoned devops wizard.
Common Pitfalls (And How to Dodge ‘Em Like a Pro)
We’ve debugged enough IIS redirect loops to write a novel, so let’s save you the pain. Here are the usual suspects:
| Mistake | Result | Fix |
|---|---|---|
| Redirect rule on HTTPS site too | Infinite loop | Only apply rule to HTTP binding (port 80) |
| No SSL cert on port 443 | Browser errors | Install and bind valid cert first |
| Hardcoded HTTP links in app | Mixed content warnings | Use protocol-relative URLs or HTTPS everywhere |
| Multiple redirect rules stacked | Unpredictable behavior | Keep it to one clean rule |
Also, if you’re behind a load balancer or Cloudflare, you’ll need to check headers like X-Forwarded-Proto instead of {HTTPS}. But for most standalone IIS setups, the standard rule works like a charm. Avoid these traps, and your forward http to https iis journey stays smooth as butter.
Testing Your Redirect Like a Real Grown-Up
Don’t just assume it works—prove it. Open PowerShell or Command Prompt and run:
curl -I http://yoursite.comYou should see:
HTTP/1.1 301 Moved Permanently
Location: https://yoursite.com/Then test the HTTPS version:
curl -I https://yoursite.comShould return 200 OK. Also, pop open Chrome DevTools → Network tab, disable cache, and reload the HTTP URL—you should see exactly one 301, then a 200. No loops, no errors. If it’s clean, go ahead and submit your updated sitemap to Google Search Console. A solid forward http to https iis setup means zero HTTP pages indexed and full SEO credit. Easy peasy.
Going Full Lockdown: Disable HTTP Entirely (Optional)
Want to go nuclear? You can **disable the HTTP binding entirely** in IIS after confirming your redirect works. Right-click your site → Edit Bindings → remove the entry for port 80. Now, only HTTPS works. This is overkill for public sites (since users still type http:// by habit), but great for internal APIs or admin panels where you control the client. Just remember: if you kill port 80, there’s no redirect—just a connection refused error. So only do this if you’re sure all traffic comes in via HTTPS. For most folks, a graceful forward http to https iis redirect is the smarter play.
Wrapping It All Up Without Losing Your Lunch
Look, configuring a forward http to https iis redirect might feel like assembling IKEA furniture in the dark—but it’s simpler than it sounds. Install the URL Rewrite module, add one clean rule, test like your job depends on it, and sleep easy knowing your users are safe. And if you’re knee-deep in web.config files and need a lifeline, our deep-dive guide on HTTPS Redirect IIS Configuration walks through advanced scenarios like load balancers and sub-apps.

Frequently Asked Questions
How to forward HTTP to HTTPS in IIS?
To forward HTTP to HTTPS in IIS, install the URL Rewrite Module and create a rule that checks if {HTTPS} is "off," then redirects to https://{HTTP_HOST}/{R:1} with a 301 status. This ensures all insecure traffic is upgraded, forming a reliable forward http to https iis setup.
How do I forward from HTTP to HTTPS?
You can forward from HTTP to HTTPS in IIS by using the URL Rewrite module or editing web.config to include a redirect rule that triggers when the request is not secure. This is the standard method for implementing a forward http to https iis policy across your entire site.
How to set HTTP redirect to HTTPS?
Set an HTTP redirect to HTTPS in IIS by adding a rewrite rule that matches all URLs and redirects them to the HTTPS version when {HTTPS} equals "off." Use a 301 permanent redirect for SEO benefits. This configuration is the backbone of any effective forward http to https iis strategy.
How to enable only HTTPS in IIS?
To enable only HTTPS in IIS, first ensure a valid SSL certificate is bound to port 443. Then either set up a 301 redirect from HTTP to HTTPS using URL Rewrite, or remove the HTTP binding entirely for internal services. For public sites, the redirect approach is preferred as part of a complete forward http to https iis implementation.
