How to use the. ashx File

When httphandler is used. the config file is configured to intercept specific requests and point to the corresponding class that implements the ihttphandler interface. However, there is another simpler way to use it. ashx file.
Create a new text file suffixed with. ashx. Assume It is named "mytest. ashx", and add the following content to the file:
<% @ Webhandler Language = "C #" class = "class type" %>
The class type must be the type that implements the ihttphandler interface, for example:
<% @ Webhandler Language = "C #" class = "mylibrary. myclass" %>

In this way, the ihttphandler class can be accessed through a request to mytest. ashx, such as http: // localhost/mytest. ashx.
