IIS7 Url Rewrite – Can I use stopProcessing=”false” with a Redirect Rule

iis-7url-rewriting

I wish to canonicalize a domain name, from bar.example.com to www.example.com (well anything that's not www.example.com). Site runs IIS7.

The problem is that certain URLs were of the form http://bar.example.com/asp/oldpage.asp?query=awesome, and have specific URL rewrite rules already in place that redirect to http://www.example.com/newpage/awesome

I want to write a rule that catches the other rules.

HERE'S THE CATCH: I have a lot of rules, and want to put this rule in the root of the site, but have additional rewrite/redirect rules in sub-folders, so I want to defer the 301 from happening until all the rules have been run.

Is this possible? Rewrites have an option to defer (stopProcessing="false") but this doesn't seem to be an option for Redirects.

Am I SOL here?

Unfortunately, I can confirm that the deferred processing (stopProcessing="false") works with rewrite actions only and is ignored by the redirect ones.

Should the number of matches having been small - but it is not, according to your question - I would have suggested you to combine them using a regex alternation. For example:

First match: ^first/a$
Second match: ^second/b$

Combined match: ^(first/a|second/b)$

Leading to something like:

<rule name="MyCombinedRule">
    <match url="^(first/a|second/b)$" />
    <action type="Redirect" url="http://www.example.com/third/c" />
</rule>

IIS7 URL Rewriting: How not to drop HTTPS protocol from rewritten URL

Here's Scott's answer with Hasan's improvements. This should cover mixed SSL/non-SSL sites. The rule basically says "if the url does not have www.example.com", do a permanent redirect to it. Essentially... you are redirecting people who visit you without www or directly to your IP address.

<rewrite>
<rules>
    <rule name="Canonical Host Name" stopProcessing="true">
        <match url="(.*)" />
        <conditions logicalGrouping="MatchAll">
            <add input="{HTTP_HOST}" pattern="^www\.example\.com$" negate="true" />
        </conditions>
        <action type="Redirect" url="{MapSSL:{HTTPS}}www.example.com/{R:1}" redirectType="Permanent" />
    </rule>
</rules>
<rewriteMaps>
    <rewriteMap name="MapSSL" defaultValue="http://">
        <add key="ON" value="https://" />
        <add key="OFF" value="http://" />
    </rewriteMap>
</rewriteMaps>
</rewrite>

In the IIS7 URL Rewrite module, can I specify in a redirect rule to not apply to http-post requests

You have access to that in the {REQUEST_METHOD} variable under the conditions.

<add input="{REQUEST_METHOD}" matchType="Pattern" pattern="POST" ignoreCase="true" negate="true" />
