Webconfig URL Rewrite to Hide Classic ASP ext but not .aspx or other ext - asp.net

Question

I have been able to hide the .asp extension, but it also removes any other extensions and points to .asp
I know this is just a config issue but have no experience of the webconfig file configuration and wonder if anyone has a quick solution to save me a few hrs!
Code as I have it below from part of webconfig file
<rewrite>
<rules>
<rule name="Hide .asp Ext">
<match url="^(.*)$" ignoreCase="true" />
<conditions logicalGrouping="MatchAll">
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
<add input="{REQUEST_FILENAME}.asp" matchType="IsFile" />
</conditions>
<action type="Rewrite" url="{R:0}.asp" logRewrittenUrl="true" />
</rule>
<rule name="Redirect .asp Ext" stopProcessing="true">
<match url="^(.*).asp" ignoreCase="true" />
<conditions logicalGrouping="MatchAny">
<add input="{URL}" pattern="(.*).asp" />
</conditions>
<action type="Redirect" url="{R:1}" />
</rule>
</rules>
</rewrite>

Answer 1

Seems to me the first rule converts everything to an .asp extension first?
Try removing the first rule.

Answer 2

Try this? Seems to work on my test server.
<rule name ="redirect .asp to none" stopProcessing="true">
<match url="(.*)\.asp$" />
<action type="Redirect" url="{R:1}" redirectType="Permanent" />
</rule>
<rule name="hide .asp extension" stopProcessing="false">
<match url="(.*)" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="{R:1}.asp" />
</rule>

You have two rules defined. It looks like the first matches on all requests and "rewrites" them to have a .asp extension. The second matches on on .asp and then performs a redirect of some kind.
What is not clear from your question is how you want to 'hide' these files. If you want to deny all requests to .asp you would be much better served adding a Request Filtering "File Extensions" https://learn.microsoft.com/en-us/iis/configuration/system.webserver/security/requestfiltering/fileextensions/index
