Don't do that unless you really need to for some reason. (see below)

I believe so.

CGI.pm and libapreq both provide methods for getting the data, you don't read 
it yourself, you just ask the module for the data and it hands it to you 
pre-parsed.

It doesn't matter, use one of the above and it'll handle it all for you and 
give you the data.

I believe libapreq is faster than CGI.pm, is that what you meant?
