I have a website where I am trying to generate a member of the day, is there anyway to cache data for a set amount of time, I know you can cache a query, just wondering if there are other methods for caching. How would you address this? This title, Simple Data Caching in ColdFusion, is a little misleading for the post. When is comes to "smart" da... read more »

This wasn't quite an Ask Ben question, but it was a question that was asked of me and I would like to have a definitive place to point people when the question comes up again. A user asked me how to get ColdFusion to end the user's session when the user closes their browser. I have discussed ending sessions before, but let's just quickly hammer ou... read more »

I have an array but it could be a list using listtoarray or vise verse is there an easy way to delete all of a particular 'value' from a list or an array. For example I have a list or array with: "1,1,1,1,1,2,2,2,2,2,3,3,3,4,4,4,4,5" And say i want to remove all instances of the number two... is there a simple way to do that? There are probably... read more »

After posting a while back about uploading a file and emailing it using ColdFusion , I was asked to put up a demo of how to upload multiple files using ColdFusion. For this demo, I am concentrating only on the upload aspect and not worrying about any emailing functionality as I believe that adding that is easy after the upload is complete. Befo... read more »

This was sort of based on an Ask Ben inquiry, so I will include it in this section, but it's not entirely accurate. Someone had asked me about passing a file to a web service and I had suggested that one of the ways to do this was to pass it using a Base64 encoding of the binary data. This would allow the data to be easily defined using XML, which... read more »

This isn't necessarily an "Ask Ben" question; Michael Appenzellar had brought up the concept of breaking up an SMS text message into multiple parts that were, at most, 120 characters each. He was having a bit of trouble breaking it up, so I thought I would throw together a quick little demo. To start with, let's create the text message that yo... read more »

I have written custom java classes take the user input from the cfform, handle the db transactions and pass back an xml object which is then parsed in CF.

Not a specific question here; some people have seen me use recursion when dealing with user defined functions and ColdFusion custom tags and have asked to demonstrate a simple example of recursion to help get more comfortable with it. Recursion is a very powerful tool that is required to solving some problems, but at the same time, when wielded im... read more »

Looking to run a CFM template asynchronously - aka: run it in the background. Gotchas: * Must work under MX 6.1 * I can't use an event gateway * Can't use CFSCHEDULE (unless you know of a way to post data to the URL) Any ideas? This reminds me of that old Polly-O String Cheese commercial where the guy walks into the pizza parlor and says some... read more »
