If you want to use that latest and greatest feature in HAProxy, you’ll probably end up having it to build it yourself. If you’re adventurous enough to run a potentially unstable development version on your server, here’s how to compile the binary.
Get the latest dev version from here: haproxy.1wt.eu/#down
Set up the build environment:
apt-get install build-essential zlib1g-dev libpcre3-dev libssl-dev
Build the binary (assuming your Linux kernel version is >= 2.6.28):
make TARGET=linux2628 CPU=native USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1
This will include OpenSSL and zlib compression support.
