Web.config URL rewrite - force www prefix and https - asp.net

Question

I'm trying to enforce https and a www prefix. However my rule doesn't fully work. Here is my rule:
<rewrite>
<rules>
<clear />
<rule name="Force https" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="off" ignoreCase="true" />
</conditions>
<action type="Redirect" url="https://www.mydomain.co.uk/{R:1}" redirectType="Permanent" />
</rule>
<rule name="Force www" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="localhost" negate="true" />
<add input="{HTTP_HOST}" pattern="www.mydomain.co.uk" negate="true" />
</conditions>
<action type="Redirect" url="https://www.mydomain.co.uk/{R:1}" redirectType="Permanent" />
</rule>
</rules>
</rewrite>
It works for redirecting http to https.
it works if I go to https://mydomain.co.uk (redirects to https://www.mydomain.co.uk)
however it DOES NOT work if I go to https://mydomain.co.uk/blah/whatever
Please can somebody advise? Thanks.

These are the rewrite rules that I use for that exact purpose. I've also added a rule to make the URL all lowercase and a rule to remove the trailing slash should one be present. This makes working with Analytics easier since it treats page.aspx and page.aspx/ as different url's. That is why I use ignoreCase=true because then it does not matter if someone uses upper case somewhere since it will be handled later on by the ToLowerCase rule
<rule name="ForceWWW" stopProcessing="true">
<match url=".*" ignoreCase="true" />
<conditions>
<add input="{HTTP_HOST}" pattern="^yoursite.com" />
</conditions>
<action type="Redirect" url="https://www.yoursite.com/{R:0}" redirectType="Permanent" />
</rule>
<rule name="HTTPtoHTTPS" stopProcessing="true">
<match url="(.*)" ignoreCase="false" />
<conditions>
<add input="{HTTPS}" pattern="off" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" />
</rule>
<rule name="RemoveTrailingSlash">
<match url="(.*)/$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Redirect" redirectType="Permanent" url="{R:1}" />
</rule>
<rule name="ToLowerCase">
<match url=".*[A-Z].*" ignoreCase="false" />
<action type="Redirect" url="{ToLower:{R:0}}" redirectType="Permanent" />
<conditions>
<add input="{URL}" pattern="WebResource.axd" negate="true" />
<add input="{URL}" pattern="ScriptResource.axd" negate="true" />
</conditions>
</rule>

Here is an example of such web.config -- it will force HTTPS for ALL resources (using 301 Permanent Redirect):
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="HTTP Redirect to HTTPS" enabled="true" stopProcessing="true">
<match url="(.*)" ignoreCase="false" />
<conditions>
<add input="{HTTPS}" pattern="off" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}/{R:1}" appendQueryString="true" redirectType="Permanent" />
</rule>
</rules>
</rewrite>
<rewrite>
<rules>
<rule name="Redirects to www.example.com" patternSyntax="ECMAScript" stopProcessing="true">
<match url=".*" />
<conditions logicalGrouping="MatchAny">
<add input="{HTTP_HOST}" pattern="^example.com$" />
</conditions>
<action type="Redirect" url="https://www.example.com/{R:0}" />
</rule>
</rules>
</rewrite>
</system.webServer>
