As explained in the ColdFusion Administrator the Request Timeout property allows us to terminate requests that take longer than the specified time. This prevents unusually long requests from occupying server resources and impairing the performance of other requests. There are two ways to control this time. The first and easiest is to set a global time for your server in the administrator. When logged in click on the settings button under Server Settings. From there locate the timeout request and change it to a value of your choice. The attribute is a number and represents seconds. If you are on shared host that this is not an option for you. Lucky for you there is a way to change this programatically. You can use the cfsetting tag and use the requestTimeout attribute. From the livedocs we can see this takes precedence over the the administrator timeout. You could set this in your application component for your entire system or you can use on a per template basis.
