https://www.mydomain.com and https://mydomain.com go to different pages - iis-6

Web Server: IIS 6.0 (ASP.Net 4.0)
I host two sites: one is the main web site and the other is the store site. Each are separate web sites in IIS. Each share the same wildcard SSL certificate. The store site uses a Host Header (store.mydomain.com) to direct traffic to it.
I want it so any URL used without the sub-domain "store" directs the user to the main web site, not the store web site.
The problem I'm experiencing is that the following URL always directs users to the default.aspx page on the store web site:
https://www.mydomain.com
Yet, these URLs correctly go to the main page on the main web site:
http://mydomain.com
http://www.mydomain.com
https://mydomain.com
What's up with the https://www that directs users to different page?
I have added a rewrite rule in the web.config file for both sites but it doesn't have any effect:
<rewrite>
<rules>
<rule name="Consistent Domain" stopProcessing="true">
<match url="^(.*)$" ignoreCase="false" />
<conditions>
<add input="{HTTP_HOST}" pattern="^mydomain.com$" />
</conditions>
<action type="Redirect" redirectType="Permanent" url="http://www.mydomain.com/{R:1}" />
</rule>
</rules>
</rewrite>

First, are you sure this is IIS6? The URLRewrite feature is part of IIS7 and would have no effect under IIS6 if present. If this is IIS6 that may well be the answer to your question.
That aside, it is difficult to answer this based on the data given. It is possible that the bindings of the sites is incorrect and resulting in the traffic going to a site you don't expect.

IIS hosted web application works fine with ssl without www, gives 404 error with www

Good morning.
I have a web application (made with angular if useful) hosted with IIS on a windows server 2016 with certificate (made with Let's Encrypts wacs) that works fine with ssl.
the problem is, if i use www the site not only appear as not safe, but also gives 404 error.
I tried the following rule on web.config to redirect to non www but without success
<rule name="Redirect WWW to non-WWW" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^example\.com$" negate="true" />
</conditions>
<action type="Redirect" url="https://example.com/{R:1}" />
</rule>
I have other rules, thats my complete webconfig file: https://pastebin.com/wRWarfCV
I think https://www.example.com and https://example.com are Different domains. you need to reissue certificate and add http://example.com as primary domain and add other domain http://www.example.com.
More information you can refer to this link: How do I reissue my SSL certificate?.

Serve specifics request in dedicated server for same domain

Asp.net Core App in IIS with its own domain served in two balanced servers.
Is it possible to have a specific controller attended in a third server only, but under the same domain?
Let's say http://MyApp.com/MyBusyController served in the third server and the rest of the app in the other two?
The reason for this is that this controller will be doing some heavy operations and it's going to get very busy, and don't want to degrade the other two servers, but have to be under the same domain.
You can use ARR load balance instead. So that URL rewrite rule can be used to manage the load balance.
https://learn.microsoft.com/en-us/iis/extensions/configuring-application-request-routing-arr/http-load-balancing-using-application-request-routing
You can create default inbound ARR_loadbalance rule and exclude the request to MyBusyController:
<rule name="ARR_MyWebFarm_loadbalance" enabled="false" patternSyntax="Wildcard" stopProcessing="true">
<match url="*" />
<action type="Rewrite" url="http://MyWebFarm/{R:0}" />
<conditions>
<add input="{REQUEST_URI}" pattern="MyBusyController" negate="true" />
</conditions>
</rule>
Then you can create reverse proxy rule for specific controller MyBusyController:

Redirect Response always redirects to the same domain

I'm writing a suite of ASP.NET Core web applications that occasionally have to redirect to one another. When testing locally, everything works fine. However, when I publish them on our staging server, the redirects always "stay" in the same host. For example, if I am on http://app1.test/ and redirect to http://app2.test/somepath, what I actually get in the Location HTTP header i http://app1.test/somepath: any URL I specify is transformed so that it "stays" in the current host name.
This doesn't happen locally, however. I've deployed the apps as Kestrel processes, and they are exposed via IIS working as a reverse proxy. May this be the cause? What should I do to fix the issue?
UPDATE
Here is the full web.config for the reverse proxy of app1.test:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="ReverseProxyInboundRule1" stopProcessing="true">
<match url="(.*)" />
<action type="Rewrite" url="http://localhost:5000/{R:1}" />
</rule>
</rules>
</rewrite>
</system.webServer>
<system.web>
<sessionState mode="InProc" />
<customErrors mode="RemoteOnly" />
</system.web>
</configuration>
app2.test's web.config is virtually the same (apart, of course, for the port numbers).
UPDATE 2
I'll try to explain better. I noticed that the target site doesn't really matter, so I'll keep things simpler: I have an action in my application that I want to redirect the user to Google. This is the action, in the Home controller:
public IActionResult ToGoogle()
{
return Redirect("https://www.google.com?q=Hi");
}
If I launch the web app locally and request http://localhost:1234/Home/ToGoogle, everything is fine: the response is a 302 Found, with the correct URL (www.google.com etc.) in the Location header.
Once I publish the app to the staging server (Kestrel app on port 5000, behind an IIS reverse proxy with the rewrite rule posted above), this is what happens instead:
What is the cause of that?
I found the solution myself. It was indeed a problem with reverse proxy.
IIS has an option to rewrite the host in response headers. The solution is described in this answer (there are addenda in other answers to that same question if your version of IIS or Windows Server is not the one specified).

URL should hit https instead of http

I am running a Windows Server, where i have hosted a site.
Now i have done the Binding with the SSL certificate for the site. But every time i hit the website URL, it goes to http instead of https. Althoough i have binded http & https with the SSL certificate.
Example -
when i try to hit abc.com
it goes http://example.com
instead of
https://example.com
Do i have to do anything more which can help me to fix this issue.
so everytime i try to visit
example.com
i will visit
https://example.com
Do anyone knows a way to fix this issue !
You need to add a redirect to make sure all traffic gets redirected, something like below. Make sure you have the URL rewrite module installed.
<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>

Azure Cloud Service redirect http to https not working (tried answers on many links)

I'm trying to do the 'simple' task of redirecting/rewriting traffic from http to https, I have one endpoint in a CloudService which is correctly configured for SSL.
I've tried many IIS rewrite rules, like the one below, but none are working. I've also tried setting up the rules via remote desktop on the IIS 8 server directly which also doesn't work.
When I enter any tag in the Azure web.config file the rewrite tag has a blue line under it with a message saying it is invalid under <system.webServer> :
<system.webServer>
...
<rewrite>
<rules>
<rule name="RedirectToHTTPS" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="off" ignoreCase="true" />
</conditions>
<action type="Redirect" url="https://{SERVER_NAME}/{R:1}" redirectType="SeeOther" />
</rule>
</rules>
</rewrite>
</system.webServer>
Any advice is much appreciated.
In order for these rules to work you have to configure both the endpoints - HTTP and HTTPS !!
If you have not configured plain HTTP endpoint on port 80, your server will never be hit by an Internet traffic, so rewrite rules will never trigger.Thus you get the timeout when you try opening the domain over plain HTTP. There is simply no process listening on port 80 when you haven't defined endpoint for it.
