IIS - Using HttpHandler for all files except for one

Question

I use a custom HttpHandler in .NET for all *.html files, however I want to create a single exception for the file foo.html , which should be handled as a static file on the hard drive. I've tried:

  <httpHandlers>
     <remove verb="*" path="*.html" />
     <add verb="*" path="/foo.html" type="System.Web.StaticFileHandler" />
     <add verb="*" path="*.html" validate="false" type="Imp.Handler" />
  </httpHandlers>

As well as:

  <httpHandlers>
     <remove verb="*" path="*.html" />
     <add verb="*" path="*.html" validate="false" type="Imp.Handler" />
     <add verb="*" path="/foo.html" type="System.Web.StaticFileHandler" />
  </httpHandlers>

However, both will cause Imp.Handler to handle foo.html requests still. What am I doing wrong?

IIS is running in Classic mode.

Answer 1

may be this method can help you,move the files to the other folder and disable httphandler for this folder.

<location allowOverride="false" path="Static">
    <system.web>
      <httpHandlers>
        <remove verb="*" path="*.htm"/>
        <!--<add verb="*" path="/foo.htm" type="System.Web.StaticFileHandler" />-->
      </httpHandlers>
    </system.web>
</location>

<httpHandlers>
     <add verb="*" path="*.html" validate="false" type="Imp.Handler" />
</httpHandlers>

i trying test this,the question is :

if i remove HttpHandler for the "*.html" in the location element,and add a other httphandler will doesn't worked .for example:

<location>
    <remove verb="*" path="*.htm"/>
    <add verb="*" path="foo.html" validate="false" type="Imp.Handler" />
</location>
