Hidden Features of ASP.NET [closed]
While testing, you can have emails sent to a folder on your computer instead of an SMTP server. Put this in your web.config:
<system.net> <mailSettings> <smtp deliveryMethod="SpecifiedPickupDirectory"> <specifiedPickupDirectory pickupDirectoryLocation="c:\Temp\" /> </smtp> </mailSettings></system.net>
If you place a file named app_offline.htmin the root of a web application directory, ASP.NET 2.0+ will shut-down the application and stop normal processing any new incoming requests for that application, showing only the contents of the app_offline.htm file for all new requests.
This is the quickest and easiest way to display your "Site Temporarily Unavailable" notice while re-deploying (or rolling back) changes to a Production server.
Also, as pointed out by marxidad, make sure you have at least 512 bytes of content within the file so IE6 will render it correctly.
