CAS authentication

webermp) — Mon, 19 Jun 2006 19:35:23 GMT

Include this file at the top of every page that you want to have CAS authentication on. Note that this only authenticates that the person signing is is a UWEC user, but doesn't take into account the role of the user. Currently the username is stored into Session[uwecNetworkID], but can be changed for each application. It also checks to see if the user has already been authenticated.

Auto Download

webermp) — Mon, 19 Jun 2006 19:42:02 GMT

Call this function, and the server will send the user a request to begin downloading a file instead of sending it through the browser (e.g. if you called the function on a PHP file, the server would allow the user to download the source code of that file instead of serving it) Of course, that's why this code contains exceptions that don't allow you to download certain files to prevent that type of thing from happening. To use, simply call the function dl_file(filename) with the filename.

MS SQL Stored Procedure from ASP

hoganbp) — Mon, 19 Jun 2006 19:31:56 GMT

This is the preferred way to call a stored procedure from ASP. The number one reason to use this method is that it is nearly self-documenting. Without looking at the SQL Stored Procedure, the developer can tell what parameters are being sent, their data types, and their sizes. Also, this method can validate the data types before they go to the SQL Server. For example, if you passed a string into a parameter requiring an adInteger data type using this method, the ASP would fail before the command was executed, saving valuable resources. This method is also required if the stored procedure returns output parameters.

Query data in chunks with ActiveRecord

ludwigaw) — Tue, 12 Feb 2008 06:56:07 GMT
