One is a page conversion class, which is implemented by static function Changfile () to convert dynamic pages to static pages.
Copy Code code as follows:

In the paging file, the background code for forurl.aspx is as follows:
protected void Page_Load (object sender, EventArgs e)
... {
Try
... {
int id = Int. Parse (request.querystring["PID");
if (Htmlproxy.changefile (ID))
... {
Response.Redirect ("Post_" + ID + ". html");
}
Else
... {
Response.Redirect ("Post.aspx?") Pid= "+ ID);
}
}
Catch... {
}
}
