web.config redirect multiple domains to one - web-config

Question

Hi i am trying to redirect my domain aliases to one domain.
I currently have this rule
<rule name="WWW Rewrite" enabled="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" negate="true"
pattern="^www\.([.a-zA-Z0-9]+)$" />
</conditions>
<action type="Redirect" url="http://www.domain.com/{R:0}"
appendQueryString="true" redirectType="Permanent" />
</rule>
It works perfect when the alias doesnt have the www in front.. how do i say redirect all that is not equal to this domain
thanks

Answer 1

Try it. I'm not sure if it works or not, I'm not great in this subject but this has been sitting here for 4 months unanswered, so I thought I'd give it a wollop.
<rule name="Rewrite domain requests" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^(www.)?([.a-zA-Z0-9]+)$" />
</conditions>
<action type="Rewrite" url="http://www.mydomain.com/url={R:1}" appendQueryString="true" />
</rule>
It's the pattern I'm unsure of. I think this says, match anything in the URL, whether with or without www, and any possible domain extension.

Add one rule for each domain. It keeps query string too:

<rule name="Domain Redirect" stopProcessing="true">
<match url="(.*)" />
<action type="Redirect" url="http://{C:1}mydomainalias.com/{R:1}" redirectType="Permanent" />
<conditions>
<add input="{HTTP_HOST}" pattern="^(www\.)?mydomain\.com" />
</conditions>
</rule>

This will solve your problem.
You have to negate the main domain to avoid a redirect loop.
<rule name="Rewrite domain requests" stopProcessing="true" enabled="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^(www.)?([.a-zA-Z0-9]+)$" />
<add input="{HTTP_HOST}" pattern="^www\.domain\.com$" negate="true" />
</conditions>
<action type="Redirect" url="http://www.domain.com/{R:1}" redirectType="Permanent" appendQueryString="true" />
</rule>
