Lighttpd Changes

lighttpd.conf

Need to copy this lighttpd.conf and light.tar.gz files in RPI camera target

lighttpd.conf:
Need to copy this lighttpd.conf file into /etc/lighttpd

light.tar.gz:
copy this into camera target
Local system : scp light.tar.gz root@camera_ip:/

camera target:

cd /
tar -xzvf  light.tar.gz

While untar this light.tar.gz file the respective files will automatically copy to usr/bin , usr/lib , usr/share directory.

Once did above steps then reboot the target.
