[cse491] reading complete requests

[Joe Amenta]

Example request:

GET /form.cgi?username=mille449&password=saved HTTP/1.0

The query string in that request would be
"username=mille449&password=saved", or in other words, everything following
the first "?" in the URL.

As for the example code, yes, that would not read the POST data... perhaps
the intent was just to show a way to handle the simple case, so that we can
build off of it?  In any case, yes, that example code will fail to read in
POST data, thus it should probably not get full credit.

To read until the request is complete... this is an example of something
that we can figure out through investigation.  One way to go about this
would be to use form.html from way back in HW1.  Set the "method" to point
to your web server, and then use print statements to figure out what the
data looks like when it comes in.  (Might be useful to use repr() on the
incoming data to see exactly what it looks like)

I don't know what "end of request" will look like myself (though I have a
couple of guesses) so at this point I can't be any more helpful than that.
