Need help analyzing apache-scalp code

["Martin Walker" <Martin.Walker () ctg com>]

All,

I'm writing a paper on the apache-scalp/apache chunk encoded
vulnerability

I havn't written a line of code in years (well, 'cept the odd script
whipped up now and again)

Can anyone give me a little help understanding the code off line?

Thanks
