I am indeed looking at that example, and basing my code off that example. But I need to do a bit more than that code does, and when adding on functionality, I became confused as to the best (or acceptable!) way to do it. The questions below were the ones that came up.

But, I realized I can do what i need just using the WOMultipartIterator, so while I still don't know if it's safe to use formValueForKey and formValueKeys in conjunction with the WOMultipartIterator, since I don't need to, I'm avoiding it.

Why not just look at the FileUpload example? Specifically, look at the DirectAction/ProcessFileUploadWithIteratorAction

I am trying to use WOMultipartIterator in a direct action (well, really in a custom request handler action, but it behaves like a direct action for these purposes). For a file upload.

I am confused as to what I have to do to avoid reading the entire file into memory. I've read over the documentation, and the "What's New in 5.2" document many many times, but I'm still confused--it's complicated.

I have a form that contains a file upload. It also contains other form key/values BEFORE the file upload. I want to read these key/values before I deal with the file upload. I also, of course, want to make sure the entire file upload is NEVER read into memory, for instance as part of the WORequest.

How do I access these non-file form values? Can I use formValueForKey, without worrying this cause my file to be read into memory? Can I call formValueForKey on my key values multiple times, without worrying this will cause my file to be read into memory? Can I call formValueKeys() without causing my file to be read into memory? Am I better off just using the WOMultipartIterator iterator to get my non-file form values, like I'm going to use it later to get my file form values? Am I even _allowed_ to combine a WOMultipartIterator with calls to formValueForKey/formValueKeys for the same WORequest?

Also, headerValueForKey() and headerKeys()... I'm okay calling these as much as I want however I want, without worrying about it causing the uploaded file to be read into memory, right? For instance, to get the content-length header.
