Describe the difference between struct and array in ColdFusion.
An array in ColdFusion is an ordered list of elements, while a struct is an unordered collection of key-value pairs. Arrays are accessed by numeric index, while structs are accessed by key.
How would you implement caching in ColdFusion?
ColdFusion provides several ways to implement caching, including the cfcache tag, which can cache page content, and the cachePut and cacheGet functions, which can cache data.
What are ColdFusion custom tags?
ColdFusion custom tags are user-defined tags that encapsulate commonly used functionality. They can be used just like built-in tags and can accept attributes and content.
Describe the difference between implicit and explicit variable scoping in ColdFusion.
Implicit scoping in ColdFusion refers to when you use a variable without specifying its scope, in which case ColdFusion searches the scopes in a default order to find the variable. Explicit scoping is when you specify the scope when you use the variable.
How would you secure a ColdFusion application?
Securing a ColdFusion application involves several steps, including validating user input, using secure protocols, encrypting sensitive data, managing sessions securely, and keeping the server and application updated.
