IIS // URL Rewrite Debacle // Redirecting one domain to two directions (hear me out)

[shine_victim]

Hey gurus, hope you are all safe and well.

 

I really need the oracles help and guidance here.

 

Scenario

I have a domain (alias.com) which is an alias of a main (website.com) IIS site.  We need:

• Requests for alias.com to be redirected to website.com
• Requests for alias.com/string to be redirected to website.com/newlocation/string

 

As I type this, it really hits home as to how simple this sounds but I have been round the mill and still no further on.

 

After many iterations of attempts but here is the logic I am working with:

Rule for redirecting alias.com/string to website.com/newlocation/string

Example:  User browses to alias.com/products and should be redirected to website.com/newlocation/products

	<rule name="Rule 1" enabled="true" stopProcessing="true">
		<match url="(.*)" />
		<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
			<add input="{HTTP_HOST}" matchType="Pattern" pattern="^alias\.com/.+$" ignoreCase="true" negate="false" />
		</conditions>
		<action type="Redirect" url="http://website.com/newlocation/{R:1}" />
	</rule>

Rule for redirecting alias.com to website.com

Example:  User browses to alias.com and should be redirected to website.com

	<rule name="Rule 2" patternSyntax="ECMAScript" stopProcessing="true">
		<match url="(.*)" />
		<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
			<add input="{HTTP_HOST}" pattern="^alias\.com$" />
		</conditions>
		<action type="Redirect" url="http://website.com/" appendQueryString="false" />
	</rule>

 

Any help or advice would be greatly appreciated.

 

Thanks heroes.

Right guys, for anyone that stumbles across this I have the solution in place now.

 

So, I wanted an alias Apex domain (www and non-www) to redirect to the main site URL BUT for any links to subdirectories and subpages of this alias domain to redirect to new location etc. (Example:  www.alias.com/products/item1/neowin-subscription) would be redirected to the main site (website.com/newlocation/products/item1/neowin-subscription).

 

Do the following to achieve this (sorry if this is really basic stuff but syntax held me back for a good few hours so putting this here for people with as much IIS URL Rewrite experience as me):

• Add bindings for alias.com & www.alias.com to your main website URL
• Open your document root of the main website
• Create a file called RewriteMaps.config
• Enter the following and save:

<rewriteMaps>
  <rewriteMap name="MyRedirects">
	<add key="/about-us" value="/newlocation/about-us" />
	<add key="/contact-us" value="/newlocation/contact-us" />
	<add key="/products/item1/neowin-subscription" value="/newlocation/products/item1/neowin-subscription" />
  </rewriteMap>
</rewriteMaps>

• Add the following to your web.config file:

        <rewrite>
        <rewriteMaps configSource="RewriteMaps.config"></rewriteMaps>
            <rules>
                <clear />
                <rule name="alias.com redirects" enabled="true">
                    <match url=".*" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{MyRedirects:{REQUEST_URI}}" pattern="(.+)" />
                    </conditions>
                    <action type="Redirect" url="{C:1}" appendQueryString="false" />
                </rule>
            </rules>
        </rewrite>

• Restart the website and hopefully you are good to go

Life is too short to be Googling IIS URL Rewrite syntax examples, regular expression options etc.
