Can I do it in Elmah and not to log certain exception types?

You have provided very good samples, but I did not find comprehensive document to describe how to use each filter type or configure element.

For example I want to skip logging all exception type System.Net.Sockets.SocketException, I tried following configuration in my web.config but it does not seem to work at all.

    <errorFilter>

      <test>

        <jscript>

          <expression><![CDATA[

// @import System.Net

BaseException instanceof System.Net.Sockets.SocketException

]]></expression>

        </jscript>

      </test>

    </errorFilter>

Try instead like this and see if it helps:

<errorFilter>

  <test>

    <jscript>

      <expression><![CDATA[

                // @assembly System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

                // @import System.Net

                $.BaseException instanceof System.Net.Sockets.SocketException

                ]]></expression>

    </jscript>

  </test>

</errorFilter>

I've also posted it online at: https://gist.github.com/2568751

I've essentially added the assembly reference (you might need to change the version number if you're not on .NET Framework 4.0) and a qualified BaseException with a dollar ($). See issue #278 that was fixed in ELMAH 1.2 SP 2 for background on why the dollar qualification is needed. If you not upgraded to ELMAH 1.2 SP 2 yet then you can use the undocumented $context instead as described in the sample web.config shipped with ELMAH 1.2 SP2.

I tried, it does not seem to block the logging of such exception.

Do you have the ErrorFilterModule registered after all other ELMAH modules?

Which version of ELMAH are you using?

Which version of ASP.NET are you using?

Are you in a dev environment? If yes, are you able to attach the debugger & see if the JScript assertion is tracing any diagnostics messages?
