not using this paradigm.
read the entire 'line' into a variable, figure out how MANY fields there and assign them appropriately knowing the name/variable of every field number.

Others may have other ideas.

If the fields vary that much, and if this file is relatively large, use awk.

Another way is store in dictionary/hash. eg Python

Code:
>>> d = {}
>>> for lines in open("input.txt"):
... 	all = lines.strip().split(",")
... 	d[all[0]] = all[1:]
... 	
>>> d
{'www.real.com': ['324kb', '1', 'MyPlace'], 'www.yahoo.com': ['423kb', '2', 'Mysite', 'Public site']}
>>>

#!/bin/ksh
oIFS="$IFS"
while read str
do
# delimeter ,
IFS=","
# parse str to the array flds using delimeter $IFS
set -A flds -- $str
IFS="$oIFS" # return org IFS
cnt=${#flds[*]} # number of values
#1st field value is value of flds[0]
# print "1st fld value = ${flds[0]} "
done < sitenames.csv
