i have an handler, in which i try to write the data received in POST to log

context.Response.AppendToLog(result)

after few hints i got i added the next settings under handlers :

<add name="test1" verb="*" path="*.ashx"  type="test1"/>

but this causing the next error which i can't find a solution for :

Server Error in '/' Application.
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
Could not load type 'test1'.

We usually register the Custom HTTP handler class with the below format in the webconfig file located C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\

<system.web>
    <httpHandlers>
      <add path="*.jpg" verb="*" type="MyNameSpace.MyClass, MyDllName" />
    </httpHandlers>
 </system.web>

This way of making the custom handler requires us to precompile the Customhanlder.cs file.

csc /t:library /r:System.Web.dll CustomHandler.cs

Besides, the ASHX file, Generic handler is a common way to achieve your requirement. There is no need to register it before applying it.

the correct place to locate the settings :

<httpHandlers>
    <add name="test1" verb="*" path="*.ashx"  type="test1"/>
</httpHandlers>
