I am going to write a cgi program which support the multithread download application such as flashget.

the cgi program is written using CGI.pm, but i don't know how the access the http header fields,such as "Range:".

if the CGI.pm doesn't support this,how i get this message in my program?

anybody can help me? thanks in advance.

the http header is like the following:

Wed Apr 11 15:33:03 2007 GET /cgi-bin/upgrade.cgi?a=2 HTTP/1.1
Wed Apr 11 15:33:03 2007 Host: 10.200.11.58

You can do it, can't remember how. Look at the CGI manpage at [search.cpan.org...]

you can do it like this (case-insensitive header names):

$range = http('Range');

the http() function just reads the ENV hash, so doing this should work also:

my $range = $ENV{'Range'};

but using the http() function/method is OK.
