// Mongoose has a limit on input buffer, which also limits maximum upload size.

// It is controlled by the MG_MAX_RECV_SIZE constant, which is set by

// default to (3 * 1024 * 1024), i.e. 3 megabytes.

// Use -DMG_MAX_BUF_SIZE=NEW_LIMIT to override it.

|
|
// Also, consider changing -DMG_IO_SIZE=SOME_BIG_VALUE to increase IO buffer
|
|
// increment when reading data.
