Hello,
I've found something strange in the mod_proxy (httpd 2.0.63) setup:
The following directive says:
http://httpd.apache.org/docs/2.0/mod/mod_proxy.html#proxyiobuffersize
The |ProxyIOBufferSize| directive adjusts the size of the internal
buffer, which is used as a scratchpad for the data between input and
output. The size must be less or equal |8192|.
LESS or EQUAL 8192...
And the code in mod_proxy.c is:
long s = atol(arg);
psf->io_buffer_size = ((s > AP_IOBUFSIZE) ? s : AP_IOBUFSIZE);
psf->io_buffer_size_set = 1;
should be
psf->io_buffer_size = ((s < AP_IOBUFSIZE) ? s : AP_IOBUFSIZE);
It's the same in 2.2.x:
else if (!strcasecmp(key, "iobuffersize")) {
long s = atol(val);
worker->io_buffer_size = ((s > AP_IOBUFSIZE) ? s : AP_IOBUFSIZE);
worker->io_buffer_size_set = 1;
}
I actually need this directive to work better with some stream data. Can
somebody confirm the modification must be done in the code and not in
the documentation ?
I attach the patch for 2.0.x and 2.2.x.
