I guess that the ReadParse is from CGI. If that is the case, multiple values under a key are concatenated together using the ASCII 0 character (NUL Byte): 

perl -MCGI -le 'CGI::ReadParse();
    print for split /\0/, $in{myname}' \
    'idx=8&args=&myname=ABCD.txt&idx=+&myname=foobar'

Output:

ABCD.txt
foobar
