I have seen this in the source too, that's why I wrote it will not work with
Apache, because most pages will be greater the 8K. Patching Apache, is one
possibility, that's right, but I just looked after the
ProxyReceiveBufferSize which Oleg pointed to, and this one sets the socket
options and therefore should do the same job (as far as the OS supports it).
Look at proxy_http.c line 263 (Apache 1.3.9):
if (setsockopt(sock, SOL_SOCKET, SO_RCVBUF,
(const char *) &conf->recv_buffer_size, sizeof(int))
I am not an expert in socket programming, but the setsockopt man page on my
Linux says: "The system places an absolut limit on these values", but
doesn't says where this limit will be?
