Web.Config - URL rewrite to WWW, HTTPS and Primary Domain - URL Chain Problems?

Question

Pretty new to this, but trying hard to understand.

I was able to redirect non-www to www, and http to https, but now I need to redirect a domain pointer to the primary. ie Domain2.com to Domain1.com. I am concerned about the URL chain and taking a hit on SEO. Should I put the domain redirect before the WWW\\https one?

<rule name="Force WWW and SSL" enabled="true" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAny">
    <add input="{HTTP_HOST}" pattern="^[^www]" />
    <add input="{HTTPS}" pattern="off" />
</conditions>
<action type="Redirect" url="https://www.domain1.com/{R:1}" appendQueryString="true" redirectType="Permanent" />
</rule>

<!-- Just add this?  Should it go in front of the other? -->
<rule name ="Redirect Domain2 to Domain1" enabled="true">
  <match url="(.*)" ignoreCase="true" />
  <conditions>
    <add input="{HTTP_HOST}" pattern="domain2.com" />
  </conditions>
  <action type="Redirect" url="https//www.domain1.com/{R:0}" appendQueryString="true" redirectType="Permanent" />
</rule>

Answer 1

Instead two rules you can create one rule with multiple conditions:

<rule name="All in one rule" stopProcessing="true">
    <match url=".*" />
    <conditions logicalGrouping="MatchAny">
        <add input="{HTTPS}" pattern="off" />
        <add input="{HTTP_HOST}" pattern="^www\.domain1\.com$" negate="true" />
     </conditions>
     <action type="Redirect" url="https://www.domain1.com{URL}" />
</rule>

This rule will do the following:

• Redirect all other domains (domain1.com, domain2.com and etc) to www.domain1.com
• Redirect HTTP to HTTPS

This rule will make only one necessary redirect instead of multiple redirects as your current rules
