To: ASP. NET 2.0 App_Offline.htm

Under the root directory of the ASP. NET 2.0 site, all requests to .aspxwill be directed to App_Offline.htm if the App_Offline.htm file exists. In addition, the address bar of the browser displays the requested. aspx URL.
In this case, we only need to copy the app_offline.htm to the root directory of the site.

Note:
(1) IIS cannot Stop.
(2) requests to the. aspxfile are automatically transferred to the app_offline.htmfile only. (if the request is a. htm file, no.

Tip: Make sure the app_offline.htm file is large enough (512 bytes) to disable the IE "friendly http errors" feature.
