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.
