OData Action Gets 404 Due To Periods In URL

Following the tutorial at:

https://www.asp.net/web-api/overview/odata-support-in-aspnet-web-api/odata-v4/odata-actions-and-functions

I encountered 404 errors until I noticed the tutorial says to change the web.config file.  My original web.config contained:

<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

while the tutorial says to change the path property to "/*" like this:

<add name="ExtensionlessUrlHandler-Integrated-4.0" path="/*" verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

It worked but then accessing a static file like default.htm caused an internal server error.  One of the tutorial's comments suggested using:

<add name="ApiURIs-ISAPI-Integrated-4.0" path="/odata/*" verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" /> 

where the path of "/odata/*" is based on what you specified as the routePrefix argument of the config.MapODataServiceRoute() call.  The verb could probably be "*" if you like.

There is more info here:

Anyhow, as the commenter of the tutorial suggested, limiting the path worked for me and life is good.
