Hi Silvio, I just tried a 4699722540 byte file with both Firefox and Chrome on GNU/Linux using 'largepost.c', and it worked without a problem.
If you've compiled your own custom application, make sure you've enabled large file support for your disk IO. That said, I've not (recently?) tested this on a 32-bit system. Still, MHD should handle large files like this. As far as file limits are concerned, the MHD_PostDataIterator is limited to 2^64-1 bytes. MHD itself has no limit as it has no concept of files and treats requests as a possibly infinite stream of data. However, this requires that the client does NOT set "Content-Length" (but use chunked encoding). If "Content-Length" is present, the limit is again 2^64-1. Note that technically HTTP doesn't impose the 64-bit limit on HTTP, but I'm not aware of any HTTP client or server supporting > 64-bit values here. Happy hacking!
