Error 404 with IIS 7.0

Question

I have a text file that I am trying to use in a browser http://files.mydomain.com/test.txtand I get:

HTTP Error 404.0 - Not found 

I double checked and the text file exists. When I add a file test.htm, I have no problem.

Can anyone help? Something tells me about this security issue.

Answer 1

You have checked the following:

• Your DNS "A" record for "files" points to the correct IP address.
• If your server uses a shared IP address across multiple sites, have you configured the HTTP host header?
• Is there a mime type for extension .txt?
• - ? .htm, ASP ISAPI StaticFile?
• , .jpg, .gif, .pdf ..

, Request Filtering

• .txt
• Allow unlisted file name extensions, .

web.config:

<system.webServer>
    <security>
        <requestFiltering>
            <fileExtensions>
                <add fileExtension=".txt" allowed="true" />
            </fileExtensions>
        </requestFiltering>
    </security>
</system.webServer>
