URL Rewrite IIS 7.5 - only for port 80

Question

I setup IIS to redirect non https traffic to https by using the rewrite wizzard in IIS. I followed the steps outlined here: https://www.namecheap.com/support/knowledgebase/article.aspx/9953/38/iis-redirect-http-to-https .

Now I'm wanting to add a condition to say if the {server_port} = 80.

I added a new condition:
Condition Input: {Server_Port}
Check if input string: matches the pattern
pattern: 80

Under conditions: Logical Grouping: match all

I then saved the rule and restarted IIS.

I'm still getting all traffic to my site redirected to https which tosses Error code: SSL_ERROR_RX_RECORD_TOO_LONG since https:// www.mysite.com:83 does not compute.

How do I write the condition to redirect only if the server port is 80?

Please be aware that I have not written my redirect in the web.config and am asking because most of the examples I've found discuss web.config. I did find a web config example that should work, but I can't figure out how to use the rewrite tool to implement this:

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

I found simple mistake in your rule condition is <add input="{SERVER_PORT}" pattern="XXXX" negate="true" /> negate="true" means it does not match pattern and it rediect to the https. to impemnet your requiremnet you could use bwlow rule:

<rule name="HTTP to HTTPS redirect" stopProcessing="true">
  <match url="(.*)" />
  <conditions>
       <add input="{HTTPS}" pattern="off" />
       <add input="{SERVER_PORT}" pattern="80" />
  </conditions>
  <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Found" />
</rule>
