I'm trying to understand how these HTML INPUT file uploads work. At what point does the PHP page take over the file, once it is fully loaded into the POST data?
My uploads are timing out when I try to upload like 150 megabytes and after about 30 minutes, but why should that have anything to do with the PHP max_input_time setting. Isn't all the processing time happening on the HTML form while the file is sent to the server and then PHP handles the file?
Isn't the only interaction between the HTML form and the server. And then later PHP gets involved once the file is fully uploaded. I'm just trying to understand how this works because couldn't I set the action of the form to a blank page and it will not make a difference, it will still take a bunch of time to upload the file and not have anything to do with PHP?
