Create a secure ashx file and compile it.

From: http://blog.sina.com.cn/s/blog_6d52f3600100qnrx.html Thank you

The default ashx format is as follows:

Code
<% @ WebHandler Language = "C #" Class = "Handler2"
%>

UsingSystem;
UsingSystem. Web;

PublicClassHandler2:IHttpHandler{

PublicVoidProcessRequest(HttpContextContext)
{
Context. Response. ContentType=
"Text/plain ";
Context. Response. Write ("HelloWorld ");
}

PublicBoolIsReusable{
Get{
ReturnFalse;
}
}

}

However, the Code may be exposed to the client.

View

Code
<% @ WebHandler Language = "C #" Class = "Handler2"
%>

We can separate the ashx file from the specific code.

Code
<% @ WebHandler Language = "C #" Class = "Handler2"
CodeBehind = "Handle2.cs" %>

Store the implemented code under the app_code folder to ensure code security.

Because

① Microsoft has set access permissions for various specific folders

② The compiled code is displayed in the dll format, so it is not easy to view the source code.
