    You're working with an HTML form and someone who shall remain nameless named the form fields badly, for example, "first name" (that's first {space} name). If you don't have the ability to change the name of the form field, how can you access these form fields in ColdFusion's form scope?

    Let's say you need to read a text file into CFML, as a variable, but you work in an environment where both CFFILE and CFOBJECT/CreateObject have been disabled by the Administrator. While CFHTTP can read it as a query, and other java tricks can get around the disabling of CFOBJECT/CreateObject, what other two simple CFML tags syntax could read the file in for you in 3 lines of code?

    Winner: Johnny Le


    <cfsavecontent variable="content">
    <cfinclude template="file_to_read.cfm"/>

    If you use Application.cfc and the cfabort tag you have to be careful in certain situations. What's the issue with Application.cfc and cfabort?

    Winner: Jason Daiger

    Answer: If you use Application.cfc and cfabort, cfabort is considered to be an error so this triggers the onError method of Application.cfc.
