The filter saves the file in the requesty body given in a multipart/form-data format, hence an input filter. I found using a filter more suitable for this purpose.
> What's reading it back specifically? Once the file is saved, the control is passed on to a handler attached to the called URI (something like /handle/upload/file) which is another process. That process operates independently on the uploaded file but relies on the custom header to obtain the name of the uploaded file. > Yes, but it is after most other processing that would be reading r->headers_in Does that imply I need to hook the filter to run first or reallly first? Right now it's hooked a APR_HOOK_MIDDLE.
