I want to do a number of 301
redirects in one request and I found this article to be helpful. However, I have a problem where http://example.com
redirects to https://www.example.com
BUT https://example.com
DOES NOT redirect to https://www.example.com
So here are my examples:
BUT http://www.example.com/app/default.aspx => http://www.example.com/app/
SEO - Remove trailing slash (doesn't work and no HTTPS as above)
All links get the trailing slash instead
http://www.example.com/app => http://www.example.com/app/
https://www.example.com/app => https://www.example.com/app/
SEO - ToLower (works fine but no HTTPS as above)
http://www.example.com/APP => http://www.example.com/app
https://www.example.com/APP => https://www.example.com/app
SEO - http canonical redirect (works 100%)
http://example.com/app => https://www.example.com/app
SEO - https canonical redirect (doesn't work at all)
https://example.com/app => https://www.example.com/app - FAILS
SEO - non-canonical redirect (Doesn't work 100%. Without this rule the stylesheet fails to load, but also other links that didn't match any of the above are not being )
https://example.com/app => https://example.com/app/
http://example.com/app => http://example/com/app/
https://www.example.com/app => https://www.example.com/app/
http://www.example.com/app => http://www.example.com/app/
This is what I have implemented and the problem is as above.
<rewrite>
<rules>
<clear />
<rule name="WhiteList - resources" stopProcessing="true">
<match url="^resources/" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
<action type="None" />
</rule>
<rule name="SEO - remove default.aspx" stopProcessing="false">
<match url="(.*?)/?default\.aspx$" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_METHOD}" pattern="GET" />
</conditions>
<action type="Rewrite" url="_{R:1}" />
</rule>
<rule name="SEO - Remove trailing slash" stopProcessing="false">
<match url="(.+)/$" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_METHOD}" pattern="GET" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
</conditions>
<action type="Rewrite" url="_{R:1}" />
</rule>
<rule name="SEO - ToLower" stopProcessing="false">
<match url="(.*)" ignoreCase="false" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_METHOD}" pattern="GET" />
<add input="{R:1}" pattern="[A-Z]" ignoreCase="false" />
</conditions>
<action type="Rewrite" url="_{ToLower:{R:1}}" />
</rule>
<rule name="SEO - http canonical redirect" stopProcessing="true">
<match url="^(_*)(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_HOST}" matchType="Pattern" pattern="^www\.example\.com$" ignoreCase="true" negate="true" />
<add input="{HTTP_METHOD}" pattern="GET" />
</conditions>
<action type="Redirect" url="https://www.example.com/{R:2}" />
</rule>
<rule name="SEO - https canonical redirect" stopProcessing="true">
<match url="^(_*)(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_HOST}" matchType="Pattern" pattern="^www\.example\.com$" ignoreCase="true" negate="true" />
<add input="{HTTP_METHOD}" pattern="GET" />
<add input="{HTTPS}" pattern="^ON$" ignoreCase="true" />
</conditions>
<action type="Redirect" url="https://www.example.com/{R:2}" />
</rule>
<rule name="SEO - non-canonical redirect" stopProcessing="true">
<match url="^(_+)(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_METHOD}" pattern="GET" />
</conditions>
<action type="Redirect" url="{R:2}" />
</rule>
</rules>
</rewrite>
This is not really a solution as I found the actual problem with IIS.
When you visit https://example.com with the rules above setup (or https canonical redirect) it will first give you a certificate error if you don't have the "naked domain" certification. If the user opt to continue, then the redirect to https://www.example.com will happen.
I think this may be happening at the "DNS Negotiation" level rather than IIS level.
