I am curious to know how webservers handle file uploads.
Is the entire file sent as a single chunk? Or is it streamed into the webserver – which puts it together and saves it in a temp folder for PHP etc. to use?

It’s just a matter of following the encoding rules so that one can easily decode (parse) it. Read on the specification about
multipart-form/dataencoding (the one which is required in HTML based file uploads usinginput type="file").Generally the parsing is done by the server side application itself. The webserver only takes care about streaming the bytes from the one to the other side.
