asp.net - IIS URL Rewrite and Web.config

Question

I don't understand anything about IIS, but am trying to solve this problem of redirecting all visitors to domain.com/page to domain.com/page.html

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.webServer>
    <rewrite>
          <rewriteMaps>
              <rewriteMap name="StaticRedirects">
                  <add key="/page" value="/page.html" />
              </rewriteMap>
            </rewriteMaps>
      </rewrite>
  </system.webServer>
</configuration>

A couple of problems arise:

1. I don't know where to even put the file. There is a User root directory, and an htdocs directory, I tried both, no joy.
2. I don't even know if the account can do rewrites, I am trying to find that out.

Answer 1

1) Your existing web.config: you have declared rewrite map .. but have not created any rules that will use it. RewriteMap on its' own does absolutely nothing.

2) Below is how you can do it (it does not utilise rewrite maps -- rules only, which is fine for small amount of rewrites/redirects):

This rule will do SINGLE EXACT rewrite (internal redirect) /page to /page.html. URL in browser will remain unchanged.

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRewrite" stopProcessing="true">
                <match url="^page$" />
                <action type="Rewrite" url="/page.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

This rule #2 will do the same as above, but will do 301 redirect (Permanent Redirect) where URL will change in browser.

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRedirect" stopProcessing="true">
                <match url="^page$" />
                <action type="Redirect" url="/page.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

Rule #3 will attempt to execute such rewrite for ANY URL if there are such file with .html extension (i.e. for /page it will check if /page.html exists, and if it does then rewrite occurs):

<system.webServer>
    <rewrite>
        <rules>
            <rule name="DynamicRewrite" stopProcessing="true">
                <match url="(.*)" />
                <conditions>
                    <add input="{REQUEST_FILENAME}.html" matchType="IsFile" />
                </conditions>
                <action type="Rewrite" url="/{R:1}.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>
