php - File downloads incomplete over slow connection -

-

i have 15mb file on website (apache webserver) downloads fine on reasonable speed connections, incomplete on slower connections (28kbytes/sec, example). size of incomplete file random, 2 13 mb. have verified behavior in both safari , firefox, on connection negligible latency. neither browser indicates user file incomplete, size smaller 15mb. have tried downloading via direct link , via php download script proper headers: same results.

has else experienced kind of issue?

if use php script sending file run phps script limit on large downloads. see php.ini max_execution_time.

so don't want read file php , echo browser.

instead redirect browser file.
