[pox-dev] how to parse HTTP to retrieve file ID

[kofi adu]

hi

i am trying to develop a POX controller to cache video data/files (rtp/udp). i 
want the switch to perform a check to determine if the udp data is in the top 
250 using the IMDB. in this case i need to parse the packet to get the src ip 
and retrieve the part that contains the movie id. how do i get the movie ID 
from the URL. because i know the URL contains the host address and the 
retrieved file ID. is there any way that i can also integrate the IMDB data 
with my POX controller  

thanks
kofi
