I need modified time for a web page, and i tried head() function from LWP::Simple interface. I wrote the following test script 
#!/usr/bin/perl
use LWP::Simple;
($content_type, $document_length, $modified_time, $expires, $server) =
+ head $ARGV0;
printf "$content_type <> $document_length <> $modified_time <> $expire
+s <> $server\n";

[download]
and then I try it: 
bash$ ./test_head.pl http://localhost/tmp
text/html <>  <> Apache/1.3.9 (Unix) Debian/GNU PHP/3.0.14 <>  <> 
bash$ ./test_head.pl http://localhost/   
text/html <> 274 <> 953031425 <> Apache/1.3.9 (Unix) Debian/GNU PHP/3.
+0.14 <>
bash$ ./test_head.pl http://localhost/index.html
text/html <> 274 <> 953031425 <> Apache/1.3.9 (Unix) Debian/GNU PHP/3.
+0.14 <>

As you can see server is not the last item of list returned by head, in fact it has no fixed position in that list.
What's wrong?
Thanks.
