<httpHandlers> Example, HttpHandlers in Web.Config ASP.Net 2.0 C#

The following default httpHandlers element is configured in the root Web.config file in the .NET Framework 2.0.

<httpHandlers>
<add... />
<remove... />
<clear/>
</httpHandlers>

add : Optional element.Specifies verb/path mapping to a handler.

clear : Optional element.Removes all handler mappings that are currently configured or inherited.

remove : Optional element.Removes a verb/path mapping to a handler. The remove directive must exactly match the verb/path combination of a previous add directive. Wildcard characters are not supported.


The <httpHandlers> settings are inherited by the application subdirectories.

The <add> directives are processed in top-down, sequential order. If two or more <add> elements specify the same verb/path combination, the final <add> overrides all others.
