Yes you get the whole content-length.
You can either operate on a list or a table. I prefer to load everything 
into a large table and parse that.
I think pdlua would be ideal for parsing text, but so far I made my own 
abstractions from Pd objects to extract numbers from particular 
locations in lists. The problem with converting things to symbols is 
that the symbol table can get filled with mostly junk symbols.
You can go line by line by scanning for 10, the ASCII line feed character.
