Prevent Coldfusion server from writing uploaded files to disk

  • 772

Coldfusion writes uploaded files to it's temporary folder, where the cffile tag will pick it up. However I want my server to ignore uploaded files and not have them written to disk at all.

How can I prevent Coldfusion from writing these files to disk?

Edit:

Or is there a way to block multipart requests in IIS (7+)?

  1. What version of ColdFusion? Assuming at least ColdFusion 9 you could use the built-in RAM file system.

    Working with in-memory files

    Memory-based virtual file system speeds up the processing of transient data. In-memory files are not written to disk and are saved on RAM. They function similar to disk files but perform faster.

    In ColdFusion, in-memory files help you to simplify the execution of dynamic code. In-memory files are supported across almost all tags and functions that take file or directory as input or output.

    You use in-memory files in the same manner as files on disk, but with a prefix ram:/// to indicate that they reside on RAM. For example, ram:///a/b/dynamic.cfm.
