It looks like for Apache 2.2.10 on Windows, mod_proxy sends
reverse proxy requests twice. I’ve verified this using two different
packet sniffers. I also tracked the problem to the ‘WSAsend’
winsock call. If you alter the APR to use the ‘send’ winsock API
call instead of the WSAsend call, then the problem goes away. I wonder if this
is a winsock bug. Ryan |
