* Set access/subscribe base URL with: CLICON_STREAM_URL_PREFIX (default https\

Browse source 
://localhost/streams).
    * Example: new stream "foo" will get access URL: https://localhost/streams/\
foo
  * Optional pub/sub support enabled by ./configure --enable-publish
    * Set publish URL base with: CLICON_STREAM_PUB_PREFIX (default http://local\
host/pub)
    * Example: new stream "foo" will get pub URL: https://localhost/pub/foo
