Code:
#!/bin/ksh
while read -r line
do
        cname=$(echo ${line} | awk -F"[/ ]" '{print $10}')
        scode=$(echo ${line} | awk -F"[/ ]" '{print $(NF-1)}')
        [[ ( ${scode} -ge 200 ) && ( ${scode} -le 399 ) ]] && {
                echo ${line} >> ${cname}_access.log
                }
        [[ ( ${scode} -ge 400 ) && ( ${scode} -le 599 ) ]] && { 
                echo ${line} >> ${cname}_error.log
                }
done < logfile

Like that?

PLEASE BE AWARE:
As rbatte1 has stated, this code may be become quite performance heavy when encountered with large files.
