# Build Apache
svn co http://svn.apache.org/repos/asf/apr/apr/branches/1.4.x srclib/apr
svn co http://svn.apache.org/repos/asf/apr/apr-util/branches/1.3.x srclib/apr-util
./buildconf # EDIT: Some commenters noted that buildconf should be run before the configure
./configure --enable-proxy=shared --enable-proxy_wstunnel=shared
make
# Copy the module to apache installation
sudo cp modules/proxy/.libs/mod_proxy_wstunnel.so /usr/lib/apache2/modules
# Create module load file
cd /etc/apache2/mods-available
sudo echo "LoadModule proxy_wstunnel_module /usr/lib/apache2/modules/mod_proxy_wstunnel.so" > proxy_wstunnel.load
# Create symbolic link to load the module
cd /etc/apache2/mods-enabled
sudo ln -s ../mods-available/proxy_wstunnel.load proxy_wstunnel.load
# Add ProxyPass to Site config
cd /etc/apache2/sites-available
