If it's possible which I think so, How do I modify my web.config to make a sub directory static -- files inside will only processed as static file, even if its name is "aspx" or something else? Thanks.
Add the following to a web.config
file in the folder containing the files you wish to be served only as static content:
<configuration>
<system.webServer>
<handlers>
<clear />
<add
name="StaticFile"
path="*" verb="*"
modules="StaticFileModule,DefaultDocumentModule,DirectoryListingModule"
resourceType="Either"
requireAccess="Read" />
</handlers>
<staticContent>
<mimeMap fileExtension=".*" mimeType="application/octet-stream" />
</staticContent>
</system.webServer>
</configuration>
