Alright I was out eating and took a break from this lmao but now I have this:
When I upload a file I first select it and then upload. More than one file is at least via gui not possible.
Working example performed by the browser
The request payload then looks like this:
-----------------------------273344254425326470862221127403
Content-Disposition: form-data; name="fileToUpload"; filename="stab.h"
Content-Type: text/x-chdr
#ifndef __GNU_STAB__
/* Indicate the GNU stab.h is in use. */
#define __GNU_STAB__
#define __define_stab(NAME, CODE, STRING) NAME=CODE,
enum __stab_debug_code
{
#include <bits/stab.def>
LAST_UNUSED_STAB_CODE
};
#undef __define_stab
#endif /* __GNU_STAB_ */
-----------------------------273344254425326470862221127403
Content-Disposition: form-data; name="submit"
Upload File
-----------------------------273344254425326470862221127403--
The file here is just something I found laying around.
The headers are

std.debug.print("{s}\n", .{content});

try req.send();
try req.writeAll(content);

try req.wait();
try std.testing.expectEqual(.ok, req.response.status);
const mssg = try req.reader().readAllAlloc(allocator, std.math.maxInt(usize));
defer allocator.free(mssg);
const out_file = try std.fs.cwd().createFile("index.html", .{});
defer out_file.close();
try out_file.writeAll(mssg);
}
My program receives the http code 200 (== .ok), however index.html is displaying the site with a notification saying that no files were uploaded.
