Hi, ap_setup_client_block() returns OK.
I think the problem is that "Content-Length" header value is 1073741824 (1 GB) and probably apache tries to receive the whole content before it passed to my module. Am I right? If yes, is there any way to tell apache to send all received data till now?

Do you check that ap_setup_client_block() returns OK? Does ap_get_client_block() return -1 on the first call? If yes, you may want to step through the function in a debugger to see what the error condition is. > How should I read client's data? > Is there any other API for it? The filter API?
