[vlc-devel] [vlc-commits] luahttp: fix scope of url handler variables

Attention lua script developers,

Please be careful when using local scope for variables at the top of
your file. If these variables are meant to be global and persist during
all the run time of the script, it would cause them to be wrongly
garbage collected after the script file is loaded and possibly mess up
all the script.

Regards,
