uricontent and pcre

[Matthew Grandison <m_grandison () yahoo com>]

Hi all,

I'm just getting started with reading the manual for
Snort.  I have a couple of options that I need further
explaination on.

Two options for the pay-load for Snort options are:
uricontent and pcre.
Can someone explain these in laymans terms. 
uricontent talks about NORMALIZING and directory
traversals..I have no idea of what this is.   And I
refered to the pcre site for more information on this,
but it just hasn't clicked yet.

Thanks all.
